How to write and call functions in MATLAB

This article is about how to write and call functions in MATLAB. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

1. Function writing

Grammar:

function [output parameter list] = function name (input parameter list)(note: there is no semicolon at the end of this statement)

notes section

function body

For example:

After writing the whole function, save the.m file, the file name is the function name.m, which should be saved as Iterative.m in the above example.

2. Call the function

Note:

1. When a function is called, the argument order should be the same as when it is defined.

2. Functions can be nested

3. Function can call itself, implement recursion

2.1 Can be called directly from the command line window

For example:

2.2 Call in other function files

For example:

3. Complete reference example

1) Function file: power.m

function [out1, out2] = power(in1, in2, n)%powout1 = (in1 + in2)^n;out2 = (in1 - in2)^n;

2)calls the file

a = 10;b = 8;for k = 0:1:10[out1 [k], out2 [k]] = power(a, b, k);end Thank you for reading!
