function [y1,...,yN] = myfun(x1,...,xM) declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN. This declaration statement must be the first executable line of the function. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.

Create Functions in Files. Both scripts and functions allow you to reuse sequences of commands by storing them in program files. Scripts are the simplest type of program, since they store commands exactly as you would type them at the command line.

Create Functions in Files. Store multiple commands in a program file that can accept inputs and return output. Types of Functions. There are several types of functions available with MATLAB ®, including local functions, nested functions, private functions, and anonymous functions. Anonymous Functions; Local Functions

Sep 18, 2020 · Learn how to create MATLAB function and why functions same time and effort when writing code. Functions are tasks or a set of tasks that are performed on a given set of input that transforms the input into a desired output.

This topic explains the term local function, and shows how to create and use local functions. MATLAB ® program files can contain code for more than one function. In a function file, the first function in the file is called the main function.

Increase code modularity and flexibility by writing custom functions. Debug functions, set the MATLAB path, and understand function precedence to resolve ambiguity in command and function names.

Add Functions to Scripts. MATLAB ® scripts, including live scripts, can contain code to define functions. These functions are called local functions. Local functions are useful if you want to reuse code within a script. By adding local functions, you can avoid creating and managing separate function files.

MATLAB ® evaluates compound expressions from left to right, adhering to operator precedence rules. Within the conditional expression of an if...end block, logical operators & and | behave as short-circuit operators.

Use matlabFunction to convert one or more symbolic expressions to a MATLAB function and write the resulting function to an M-file. You can then use the generated M-file to create standalone applications and web apps using MATLAB Compiler .

MATLAB ® includes a wide range of predefined functions for computational tasks. For basics on how to call these functions, see Calling Functions. As you write code, you can define your own functions to reuse a sequence of commands.
