Detailed Description
The invention is described in further detail below with reference to the following examples of the drawings.
The calculator in the embodiment comprises an operation processor, a storage module, a display module and a key module, wherein the storage module, the display module and the key module are respectively in electric signal connection with the operation processor.
The arithmetic processor can perform various arithmetic operations such as general addition, subtraction, multiplication, division, vector operation, matrix operation, and the like. The storage module can store various data, such as input calculation formulas, calculation results, working programs of the computer and the like. And data transmission is carried out between the storage module and the operation processor in real time. The display module can display information to be displayed based on the control of the arithmetic processor. The key module comprises a number key, an operation symbol key, a moving direction key, a working mode key and other keys. In this embodiment, a special vector calculation mode key is provided based on the vector calculation work to be performed, and the calculator can be caused to enter the vector calculation work mode by operating and inputting the vector calculation mode key. Of course, the calculator can enter the vector calculation operating mode through a combination key and the like based on program setting.
In the present embodiment, a program capable of executing the vector calculation method is stored in the memory, and the arithmetic processor can fetch and execute the program in the memory.
As shown in fig. 2 to 4, the calculator described above performs input and calculation of a vector calculation formula by using the following vector calculation method.
When a user needs to perform vector calculation, firstly, the operation processor enters a vector calculation working mode based on a vector calculation mode command input by the key module through a vector calculation mode key on the operation module. In order to facilitate the user to know the current working mode state of the calculator and avoid the situation that the user cannot obtain whether to enter the vector calculation working mode, after the operation processor obtains the vector calculation mode command input by the key module, the operation processor controls the display module to display the working mode information in the vector calculation mode. In this embodiment, the working mode information corresponding to the vector calculation mode is a character "vector". If the user successfully inputs the vector calculation mode key signal, the text 'vector' is displayed on the display module. According to specific design, the character vector can be displayed at the lower right corner of the screen, so that the influence on the display of other information is avoided. If the user does not successfully input the vector calculation mode key signal, the display of the character 'vector' on the display screen is not performed, and at the moment, the user can input the vector calculation mode key again until the calculator successfully enters the vector calculation mode.
After the calculator successfully enters a vector calculation mode, according to a vector calculation formula for performing vector calculation as required, a user directly inputs each vector data and a calculation symbol in the vector calculation formula through a key module, wherein the vector data usually comprises brackets, numbers and the like, and the number of the numbers represents the dimension of the vector. In order to distinguish the dimensional numbers in the vector and make the expression of the vector data more consistent with the expression mode commonly used in books, in this embodiment, when the user inputs the vector data, the user inputs "," between the dimensional numbers in the vector data through the key module, thereby realizing the division of the dimensional numbers in the vector data. The input sequence of the brackets, the numbers and the commas can be carried out according to the personal habits of the user. The calculation sign of the vector usually includes "X- +" which respectively represents the inner product, the outer product, the subtraction and the addition of the vector.
In the process of inputting the vector calculation formula, the display module displays the input vector data and the calculation symbol in real time in the input process of the vector calculation formula. In order to facilitate the user to determine the input position or modify the data and other requirements, when the vector data and the calculation symbols are carried out, the display module displays a cursor for confirming the input position, and meanwhile, the cursor position is adjusted through the direction key input by the key module. The cursor-based input operation is the same as the basic numeric calculation input operation of the existing calculator. Thus, each vector data and calculation symbol are input respectively until a complete vector calculation formula is input.
In order to better accord with the expression mode of vector calculation of books and facilitate the user to visually check the vector calculation formula, when the vector data are input, the display module transversely displays the vector data and directly determines the dimensionality of the vector data based on the number of the input data. Thus, it is not necessary to perform complicated operation steps such as name definition, dimension definition, input of a vector name and a calculation symbol of each vector data before the vector calculation formula is input.
After the vector calculation formula is input, the user operates the calculation command in the key module, and if the calculation command is usually the "=" key. The arithmetic processor calculates the input vector formula based on the arithmetic command input by the key module, and controls the display module to display the calculation result. In order to facilitate the corresponding relationship between the corresponding vector calculation formula and the calculation result and facilitate the user to check, the operation processor controls the display module to simultaneously display the vector calculation formula and the calculation result.
In addition, there is also a problem that the vector calculation formula input by the user is wrong, and particularly, when inputting a complicated vector calculation formula, the user cannot timely acquire information of the wrong input of the vector calculation formula. Therefore, after the operation processor obtains the operation command, whether the vector calculation formula accords with the vector operation rule or not is judged, if yes, the operation is carried out to obtain the calculation result, and if not, the operation processor controls the display module to display the prompt information of the input error of the vector calculation formula and simultaneously displays the prompt information of how to return or cancel. Therefore, the user can operate the corresponding return key to return to the input interface of the vector calculation formula according to the requirement of the user, or the user operates the cancel key to cancel the current vector calculation, so that the display interface returns to the interface before entering the vector calculation mode or the initial interface to be input of the vector calculation mode.
The vector calculation working method of the calculator can directly input the vector data and the calculation symbols among the vector data based on the vector working mode when the calculation of vector calculation is carried out, the number of the vector data and the dimension of each vector do not need to be defined, the vector calculation working method can be directly determined according to the input vector data, the operation steps are few, and the input operation is simpler and more convenient. And each vector data does not need to use a vector calculation formula formed between corresponding definition names and operation symbols, the operation steps are few, the input operation is simple and convenient, and the display module can directly display the vector calculation formula formed by each vector data and the calculation symbols, so that the viewing is more visual and the vector calculation expression mode of the books is more accordant.
