Compiling and calling of MATLAB Functions

Write a function in MATLAB and call the Function Method in the main program.

 

It is the same as other programming languages,Sub-functions and primary functions must be stored in different files.,The file name is the function name..Files must be saved in current directory before calling.

Basic Function Structure:

Function [return Variable list] = function name (input variable List)

% Annotation statement

Detection of input and return variable formats

Function body

 

% -------- Example -----

Main function main. m
Y = test (X)
Sub-function test. m (the file name is the function name)
Function Z = test (X)
Z = x. * X;

% ------- Multi-dimensional output --------

[A, B, c] = AA (m, n)

 

In addition, there are recursive calls, that is, the function itself can be called within the function;

Variable input/output count processing.

Function A = convs (varargin)

A = 1;

For I = 1: length (varargin)

A = Conv (A, varargin [I]);

End
