Matlab Function is defined as is a set of instructions that performs specific operations in Matlab, functions need a separate file in Matlab. It is implementation divided into three parts declaration of a function, calling a function and definition of function means function body. Inline Functions One downside to Matlab functions in m-files is the proliferation of files resulting from having each function in it’s own file For simple functions, this can be avoided with an inline function.
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.
You can save your function:
Matlab Function File
In a function file which contains only function definitions. The name of the file must match the name of the first function in the file.
In a script file which contains commands and function definitions. Functions must be at the end of the file. Script files cannot have the same name as a function in the file. Functions are supported in scripts in R2016b or later.
Matlab Function Optional Input
Files can include multiple local functions or nested functions. For readability, use the end keyword to indicate the end of each function in a file. The end keyword is required when:

Matlab Function List
Any function in the file contains a nested function.
The function is a local function within a function file, and any local function in the file uses the
endkeyword.The function is a local function within a script file.
