The body of a function can include valid MATLAB expressions, control flow statements, comments, blank lines, and nested functions. Any variables that you create within a function are stored within a …

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 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.

The at symbol (@) creates handles to anonymous and named functions, and is also used to call superclass methods from within a subclass.

Add functions to scripts to reuse code within a script and avoid creating and managing separate function files.

Use a function handle to create an association to a named function or an anonymous function.

For example, create a function in a file named makeParabola.m. This function accepts several polynomial coefficients, and returns a handle to a nested function that calculates the value of that …

Create two symbolic matrix functions to represent the functions F (X, A) and ∂ F (X, A) / ∂ X T. When creating the symbolic matrix functions, keep existing definitions of the symbolic matrix variables X …

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.

This MATLAB function returns a row vector of evenly spaced points between x1 and x2.
