The technical scheme in this application embodiment is to solve the problem that the difficulty of controlling mathematical tool software by a user is high, and the overall thought is as follows:
the method comprises the steps that a calculation formula input by a user is obtained through an obtaining module, and because the calculation formula input by the user comprises pasting the calculation formula and selecting a formula template to be filled into the calculation formula, the calculation formula needs to be preprocessed, the preprocessed calculation formula unifies the formats, then the preprocessed calculation formula is input into a matching module, the calculation formula is matched with a formula pre-stored in a mathematical library through the matching module, the main matching method is that characters in the calculation formula and character variables in the formula are subjected to complete matching or segmented matching retrieval comparison, the calculation formula which cannot be successfully matched is subjected to error reporting processing, and the calculation formula is returned to the obtaining module for the user to input the calculation formula again; after the formulas in the mathematical library are successfully matched, the formulas are ordered according to the operation priority, the calculation formulas corresponding to the formulas are sequentially calculated according to the ordering order, then the output module displays the result obtained after the calculation process, and the judgment module judges the reset condition according to whether the user needs to continue operation or not, namely, if the user needs to continue inputting the calculation formulas, the reset is carried out to the acquisition module, and if the user needs to continue inputting the calculation formulas, the operation is ended, so that the aims of supporting the user to input more complex formulas, increasing the way of inputting the calculation formulas by the user and simplifying the difficulty of inputting the calculation formulas are fulfilled.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
As shown in fig. 1, a flowchart of a mathematical tool software control method provided in an embodiment of the present application is applied to a mathematical tool software control device, and the method includes the following steps: s1, acquiring calculation type input by a user and preprocessing: reading a calculation formula input by a user, and preprocessing the calculation formulas of various input forms; s2, matching formulas in a mathematical library according to the calculation formula: according to the input calculation formula, automatically matching the formula in the mathematical library, if the input calculation formula is matched with the formula contained in the mathematical library, directly entering S3 for calculation, if the input calculation formula is not matched with the formula in the mathematical library, sending out an error prompt, and returning to S1; s3, processing a calculation formula according to a formula: according to the matched formula, corresponding calculation processing operation is carried out; s4, outputting a processing result: outputting the result after calculation processing to a user; s5, resetting judgment: judging whether the calculation process needs to be returned to S1 to continue, and if so, returning to S1; otherwise, the operation is ended.
Further, the manner in which the formula is input in S1 includes pasting the formula and selecting the formula template to be filled into the formula, wherein pasting the formula refers to copying the formula from other pages and pasting the formula into the input box, selecting the formula template to be filled into the formula refers to providing the formula template to the user through the mathematical library, and then the selected formula will be rewritten to the data therein by the user.
Furthermore, after the paste calculation formula is obtained, the text format needs to be preprocessed through a conversion algorithm, the text format of the formula is unified, and the specific algorithm formula for converting the unified format is as follows:
in the above-mentioned formula(s),
is a conversion function, the input content is +.>
Wherein g represents the formula of the original text format of the formula,/->
Representing the type of the i-th computational original text format,/->
Text content representing the i-th computational original text format,/->
Representing the target text format.
In this embodiment, the specific algorithm formula for converting the unified format converts the types of different computational original text formats (such as MathML, microsoft Word, image, etc.) into the LaTeX format, the formula is suitable for the user to input once after pasting the computational formulas of multiple format types for subsequent processing, and if the computational original text format has only one type, the formula can be simplified as follows:
further, the formula template is selected to be filled into a calculation formula, characters in the original formula template are replaced through a rewriting algorithm, and a new calculation formula V is obtained as an input calculation formula:
in the above formula, f represents a calculation formula generation function,
representing a formula template string,/->
Representing dictionary type data including variables and parameters appearing in the formula and their corresponding values, ++>
Representing a set of mathematical functions in a mathematical library.
Further, as shown in fig. 2, in a specific implementation process diagram of the computational formula generating function provided in the embodiment of the present application, a specific implementation process of the computational formula generating function is: step 1, replacing placeholders in a formula template character string with corresponding numerical values to obtain a new calculation formula expression; step 2, analyzing the function call in the calculation formula and converting the function call into a corresponding function object in the mathematical library; and 3, replacing function calls in the calculation formula by using the function objects in the mathematical library to generate an executable new calculation formula.
In this embodiment, first, according to the formula template and the parameter dictionary selected by the user, the calculation formula generating function replaces the parameters and variables in the formula template with corresponding values to generate a new calculation formula, for example, if the formula template is a+b, the value of a in the parameter dictionary is 2, and the value of b is 3, the calculation formula generator generates a new calculation formula of 2+3.
In the new calculation formula, some formulas or function calls may be included, such as \sin (x) or \log (x), etc. Because the function in the mathematical library is not necessarily the same as the name of the function call in the formula, the formula generator needs to traverse each function call in the formula and convert it to a corresponding mathematical function, e.g., if the formula contains a sin (x) function call, but the name of the function in the mathematical library is sin, the function call sin (x) needs to be converted to a sin (x) function.
Once the function calls in the formula are converted to mathematical functions by the formula generator, the function calls may be replaced with functions in the mathematical library, each function call in the formula may be traversed by the formula generator and replaced with a corresponding mathematical function, and the replaced formula may then be saved to memory for execution.
Further, as shown in fig. 3, in a specific flowchart of a formula in the automatic matching math library provided in the embodiment of the present application, a specific flow of a formula in the automatic matching math library in S2 is as follows: step 1, complete matching: for a simple calculation formula, searching character variables in a formula corresponding to the matching in a mathematical library according to the character sequence of the input calculation formula, if the complete matched formula can be searched for by uninterrupted characters, transmitting the calculation formula and the formula matched with the calculation formula into the S3 for processing, and if the complete matched formula is not searched for in the mathematical library, transmitting the calculation formula into the step 2 for continuous processing; step 2, segment matching: for the complex calculation formula, the calculation formula needs to be subjected to segment matching, the most conforming formula of the character variable is searched in the mathematical library from the first character according to the character sequence of the input calculation formula, namely, the first segment search is performed, when the character variable which does not conform to the most conforming formula is searched, the formula search is suspended, the next segment search is performed from the first character variable, namely, the second segment search is performed, the subsequent search is analogized, when a completely conforming formula is searched in a certain segment search, the formula obtained by the segment search matching is returned to the previous segment search as a character variable, the previous segment search is continued until the calculation formula is searched, all the searched formulas matched with the calculation formula are saved, the position of the calculation formula segment and the segmented formula list are recorded, all the segmented formulas are ordered according to the operation priority, if the completely conforming formula is not found, the calculation formula is input into the step 3 for continuous processing; step 3, outputting a result: after the calculation formula is matched with the formulas stored in the math library in the step 2, if no matched formulas are found, an error prompt is sent out, and the step 1 is returned to acquire the calculation formula again.
In the embodiment, the accuracy of matching is greatly improved by carrying out complete matching and then carrying out a process of segment matching; when the segments are matched, the calculation formula of each segment can be matched with the most conforming formula from the mathematical library according to the similarity, so that the condition that the calculation formulas cannot be matched is avoided, and the probability of successful matching is improved; for the calculation formula which cannot be completely matched, the process can continue segment matching or return to S1 to acquire the calculation formula again so as to enhance matching fault tolerance, thus, when matching fails, the program can not be directly ended, but the opportunity of re-input is provided, and the time and energy for restarting the program due to the matching failure of a user are reduced; because the method of combining automatic matching and segmented matching is used, the program supports a more complex calculation formula of matching, the matching speed is increased, and the method is favorable for processing large-scale calculation formula matching.
Further, the processing procedure of the processing calculation formula in S3 is that when the received calculation formula is that the complete matching is successful, the calculation formula is processed according to the formula in the math library matched with the received calculation formula, when the received calculation formula is that the segment matching is successful, the position of the calculation formula segment and the formula list of the segment are received, the corresponding segment calculation formula is obtained and divided according to the position of the calculation formula segment, the priority of the corresponding formula of each segment calculation formula is calculated and processed according to the formula.
In this embodiment, in S3, the specific procedure of processing the calculation formula is as follows: for a calculation formula which is successfully matched, calculating the calculation formula according to a formula in a math library matched with the calculation formula, specifically, extracting symbols and numerical values in the calculation formula, and calculating according to an operation sequence in the formula to finally obtain a result of the calculation formula; for a calculation formula with successful segment matching, firstly, receiving the position of the calculation formula segment and a formula list of the segment, obtaining and dividing a corresponding segment calculation formula according to the position of the calculation formula segment, and then calculating and processing the segment calculation formula according to the priority of the corresponding formula of each segment calculation formula; when processing the segment calculation formula, a recursive mode can be adopted to calculate the expression in the internal brackets, then calculate the value of the whole segment expression according to the priority of the operator, and in the calculation process, the operator and the numerical value can be stored and processed by means of data structures such as stacks and the like.
