Detailed Description
Referring to fig. 1, fig. 1 is a schematic structural diagram of a multi-mode calculus calculation device in a hardware operating environment according to an embodiment of the present invention.
As shown in fig. 1, the multi-modal calculus calculation device may include: a processor 1001, such as a controller or microprocessor, a communication bus 1002, a user interface 1003, and a memory 1004. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as an interface button. The memory 1004 may be a high-speed RAM memory or a non-volatile memory (non-volatile memory).
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the apparatus for acquiring cluster information of signal impulse responses and may include more or less components than those shown, or some components in combination, or a different arrangement of components. The processor 1001 of this embodiment may also be combined with a rom to perform complex operations, and have more ram units to store input programs and data
As shown in fig. 1, the memory 1004, which is a storage medium, may include therein an operating system, a user receiving module, and a multi-mode calculus calculation program.
It is to be understood that the multimode calculus calculation device of the present embodiment may be a calculator for performing calculus calculation; the apparatus of the present invention performs calculus calculations in different modes by the processor 1001 calling a multi-mode calculus calculation program stored in the memory 1005.
Referring to fig. 2 and fig. 2, a flow chart of an embodiment of a multi-mode calculus calculation method according to the present invention is shown.
In this embodiment, the multi-mode calculus calculation method includes the following steps:
step S10: and responding to current character string information input by a user, and calling a preset interface function to judge whether the format of the current character string information meets a preset integral format condition.
It should be noted that the main execution subject of the present embodiment is the processor of the above-described multi-mode calculus calculation device.
In this embodiment, an object-oriented programming design is taken as an example, and in the object-oriented programming design, a standard input interface needs to be designed, where the input interface has a function of analyzing character information input by a user.
Accordingly, the input interface can be understood as a subroutine program loaded in the above multi-mode calculus calculation program, and the corresponding input interface of the subroutine program is shown in fig. 6; there is no requirement for the input box in fig. 6 to enable free input by the user. The input interface of fig. 6 may have several input boxes or only input boxes. That is, the entire integration information may be input in one block or may be input in several blocks. To achieve this free input function, the key is the data collection of the input interface.
In specific implementation, a preset interface function is called to traverse the current character string information in response to the current character string information input by a user, and whether the format of the current character string information meets a preset integral format condition or not is judged according to a traversal result.
Step S20: and when the format of the current character string information meets a preset integral format condition, judging that the current character string information is calculus information.
Specifically, when a character string matched with the integrand format and the parameter format exists in the traversal result, the current character string information is judged to be calculus information.
Further, in this embodiment, when the format of the current character string information satisfies the preset integral format condition, after the step of determining that the current character string information is calculus information, the method further includes:
acquiring textbox controls triggered by the current character string information and unit calculus information corresponding to each textbox control, and acquiring preset priorities among the textbox controls;
setting an initial target variable S;
and assigning unit calculus information corresponding to each textbox control to the initial target variable according to the sequence of the preset priority, and taking an assignment result as target calculus information.
It can be understood that, the priority of each input box is set in advance in the embodiment, and the implementation may use the sequence of the input boxes counted from top to bottom in fig. 6 as the preset priority among the textbox controls.
The information of the first input box is received by the variable stage1, the information of the second input box is received by the variable stage2, the information of the third input box is received by the variable stage3, and the information of the fourth input box is received by the variable stage4.
stage1, stage2, stage3 and stage4 have preset binding relations with the text box controls; stage1, stage2, stage3 and stage4 are all used for receiving unit calculus information. Once the user clicks the "calculate points" button, the collection of user input points information for the system is as follows:
initializing variables
If it is not
Then S = stage1 is executed;
if it is not
The collection process is as follows: if it is
Then S = S + ',' + stage2; if it is
Let S = stage2;
if it is not
The collection procedure is as follows: if it is
Then S = S + ',' + stage3; if it is
Let S = stage3;
if it is used
The collection procedure is as follows: if it is
Then S = S + ',' + stage4; if it is
Then S = stage4.
From the above process, it can be seen that the multi-mode calculus calculation program can collect all the calculus information inputted by the user and ensure that the input of the user is free.
Step S30: and identifying a target identifier from the current character string information, and segmenting the current character string information according to the target identifier.
In a specific implementation, the target identifiers may be operation symbols or punctuation symbols (for example, comma "," or an operator "< =" or less than or equal to) common to product classifications of constant integral, double integral, and triple integral, and the current string information may be segmented by the target identifiers.
Step S40: and selecting a corresponding integral calculation mode from the preset interface function according to the segmentation result, and carrying out calculus calculation on the current character string information through the integral calculation mode.
It should be noted that, in this embodiment, the default settings are performed on the fixed point, the double point, and the triple point, and are encapsulated in the preset interface function, where the default settings include:
firstly, the selection of the fixed point calculation method needs to make the following appointment settings in order to identify the fixed point information input by the user:
(1)S＝s 1 s 2 …s n s is current character string information, and data on the right of the equal sign represents an integral calculation mode of a user;
(2) f1 represents a position in S where '< = x < =' is present;
(3) f2 represents the position in S where '< = y < =' is present;
(4) f3 represents the position in S where '< = x < =' is present;
(5) ft1 represents the position of the 1 st ',' in S;
let S = S 1 s 2 …s n If it is the integration information input by the user, the segmentation process for the character string S is as follows:
step one, if f1 > 0, f2=0 and f3=0, it means to integrate the variable x:
(1) If the user enters "f (x), a < = x < = b", the calculation is done directly;
(2) If the user inputs a < = x < = b, f (x), it becomes "f (x), a < = x < = b", and then the integral is determined;
step two, if f1=0, f2 > and f3=0, it means that the variable y is integrated:
(1) If the user enters "f (y), c < = y < = d", the calculation is done directly;
(2) If the user enters c < = y < = b, f (y), then it becomes "f (y), c < = y < = d", and then the integral is determined;
step three, if f1=0, f2= and f3 > 0, it means that the variable z is integrated:
(1) If the user enters "f (z), p < = y < = q", the calculation is done directly;
(2) If the user inputs p < = z < = q, f (z), it becomes "f (z), p < = z < = q", and then the integral is determined.
Secondly, selecting a double integral calculation method, and in order to identify double integral information input by a user, making the following appointment settings:

(2)f 2 a position indicating that a substring '< = y < =' exists in the information input by the user;
(3)f 3 a position indicating that a substring '< = t < =' exists in the information input by the user;
(4)f 4 a position indicating that a substring '< = yx < =' exists in the information input by the user;
(5)f 5 a position indicating that a substring '< = xy < =' exists in the information input by the user;
(6)f 6 a position indicating that a substring '< = rt < =' exists in the information input by the user;
(7) fs1 represents the position of the first comma in the information input by the user;
(8) fs2 represents the position of the second comma in the information input by the user;
(9) stage1 represents variables used to store y1 (x) < = yx < = y2 (x) or x1 (y) < = xy < = x2 (y) or r1 (t) < = rt < = r2 (t);
(10) stage2 represents the variables used to store a < = x < = b or c < = y < = d or α < = t < = β;
(11) func represents a variable used to store the binary function f (x, y);

(5) If s is q = ',', then perform q = q-1;
(6)stage1＝s p s p+1 …s q ；
(7) Let p = q = f11;
(8) Repeating p = p-1 until s p = ',' or p = 1;
(9) Repeatedly performing q = q +1 until s q Or p = n;
(10) If s is p = ',', then p = p +1 is performed;
