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.

This type of function must be defined within a file, not at the command line. Often, you store a function in its own file. In that case, the best practice is to use the same name for the function and the file (in this example, fact.m), since MATLAB ® associates the program with the file name. Save the file either in the current folder or in a ...

Function Precedence Order. To determine which function to call when multiple functions in the current scope have the same name, MATLAB uses function precedence order. Update Code for R2019b Changes to Function Precedence Order; Add Help for Your Program

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.

That is, when you call a function or method within a program file, MATLAB checks whether the function is a local function before looking for other main functions. Therefore, you can create an alternate version of a particular function while retaining the original in another file.

You can create handles to anonymous functions. An anonymous function is a one-line expression-based MATLAB function that does not require a program file. Construct a handle to an anonymous function by defining the body of the function, anonymous_function, and a comma-separated list of input arguments to the anonymous function, arglist. The ...

To create a script or live script with local functions, go to the Home tab and select New Script or New Live Script. Then, add code to the file. Each local function must begin with its own function definition statement and end with the end keyword. The functions can appear in any order and can be defined anywhere in the script.

Create Symbolic Functions. Symbolic functions represent math functions. Use symbolic functions for differentiation, integration, solving ODEs, and other math operations.

Also, matlabFunction can create a file that accepts numeric arguments and evaluates the symbolic expression applied to the arguments. The generated file is available for use in any MATLAB calculation, whether or not the computer running the file has a license for Symbolic Math Toolbox™ functions. Generating a Function Handle

The sibling function logspace generates logarithmically spaced values. When you create a vector to index into a cell array or structure array (such as cellName {:} or structName (:). fieldName ), MATLAB returns multiple outputs in a comma-separated list.
