Description. 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.
Functions. 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. For instance, create a function in a program file to calculate the area of a circle. rSquared = R.^2;
Function Creation. Create functions, including anonymous, local, and nested functions. Functions contain one or more sequential commands and can accept inputs and return outputs. When you have multiple lines of code, use the function keyword to define a function within a file. For instance, this function adds tax to a price.

s = @(x) sin(1./x); This function has a single input, x. The @ operator creates the function handle. You can use the function handle to evaluate the function for particular values, such as. y = s(pi) y =. 0.3130. Or, you can pass the function handle to a function that evaluates over a range of values, such as fplot:
if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional.
Anonymous Functions What Are Anonymous Functions? An anonymous function is a function that is not stored in a program file, but is associated with a variable whose data type is function_handle. Anonymous functions can accept multiple inputs and return one output.
Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool. This function fully supports thread-based environments.
Another option for storing functions is to include them in a script file. For instance, create a file named mystats.m with a few commands and two functions, fact and perm. The script calculates the permutation of (3,2). function p = perm(n,r) p = fact(n)/fact(n-r); end function f = fact(n) f = prod(1:n); end.
Mathematical Functions. Logarithms and special functions. Use a wide variety of mathematical functions in your computations — from basic functions, such as sine and cosine functions, to special functions, such as the Riemann zeta function and Bessel functions.
