MATLAB Program structure: Sequential structure "1"

Sequential structure: Execute commands sequentially, generally involving data input, data calculation or processing, data output and so on. 1. Data entry:Function: inputPrompt for user input. The left side of the equation valueCase NUM = input (PROMPT)Form one: A=input (' Value of input variable a '); After execution, scree display: Enter the value of the variable A, enter the value and return, the value of a is saved to the variable A; form two: A=input (' input matrix A '); after execution, scree display: input into matrix A; Enter and return, the matrix is saved to A; the left side of the equation is stringCase STR = input (PROMPT, ' s ')Returns the entered text as a MATLAB string, without evaluating expressions. Form: name=input (' What ' s your name? ', ' s '); After execution, scree shows: What's your name?; After entering the character, the character is saved to the name; Note: Prompt:use ' \ n ' to indicate Eachnew line. Contains a backslash: ' \ \ ', containing ' way: '; Example: reply = input (' Does want more?        y/n [Y]: ', ' s ');        If IsEmpty (reply) Reply = ' Y '; End If the prompt does not enter any value, then reply=y; 2. Output of the dataFunction: disp (output Item)The DISP function does not display the matrix name if the output item in the base is either a string or a matrix. Form one: a= ' Hello,tom '; Disp (A); Output: Hello,tom form two: a=[1,2,3;4,5,6;7,8,9] disp (A); output: 1 2 3 4 5 6 7 8 9
3. Program Pause function: Pause (delay number of seconds) such as direct pause, will be paused until after pressing any key to continue to run; the execution of the program can press: CTRL + C can be used to view the program rub the results or view the output graphics;
