This article mainly introduces how matlab program design, has a certain reference value, interested friends can refer to, I hope you read this article after a great harvest, the following let Xiaobian with you to understand.

MATLAB programming

Basic requirements:

(1)Learn Matlab M file preparation methods, including command files and function files. Understand debugging commands and debugging methods of M pieces;(2) Master Matlab program structure (sequence structure, loop structure and branch structure) and flow control statements skillfully. OutlineM-file; Input and output of data; Programming; Function files; Global and local variables

1.M file

MATLAB language program, called M file. M files have two types: command files and function files. Command file: No input parameters and no output parameters returned. Function file: can input parameters, can also return output parameters.

Input function: used to input a parameter to the computer. Call format: A=input(prompt information, option); Note: 's' option allows the user to enter a string. For example, if you want to enter a person's name, you can use the command

xm=input('What''s your name:','s')

pause function: suspends execution of the program. Call format: pause(seconds of delay) Note: If you omit the delay time and use pause directly, the program will pause until the user presses any key and the program continues to execute.

Disp function: command window output function. Call format: disp(output item) Note: Output item is string or matrix. for example

A='Hello,MATLAB';disp(A)

Output: Hello,MATLAB

2. programming

- For statement:

Format:

for loop variable = expression 1: expression 2: expression 3 loop body statement end

Note: The value of Expression 1 is the initial value of the loop variable, the value of Expression 2 is the step size, and the value of Expression 3 is the final value of the loop variable. Expression 2 can be omitted when the step size is 1

while statement

Format:

while (conditional) loop body statement end

According to the expression for y in Example 3.6, find: (1)y
