Help Center Help Center. 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. 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 Rb or later. 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.

Calling the function with a vector that contains an element that is NaN violates the input argument declaration. Function avg is a local function.

Similar to live scripts, live functions allow you to reuse sequences of commands by storing them in program files. Live functions provide more flexibility, though, primarily because you can pass them input values and receive output values. If you have an existing function, you can open it as a live function in the Live Editor. Opening a function as a live function creates a copy of the file and leaves the original file untouched. To open an existing function.

Alternatively, if you want to define a one-line function to pass to another function—for instance, a mathematical expression to pass to the integral function—you can create an anonymous function. Store multiple commands in a program file that can accept inputs and return output. To determine which function to call when multiple functions in the current scope have the same name, MATLAB uses function precedence order. Add help text to your program that displays in the Command Window when you use the help function. This topic describes how to dot index into temporary variables created by function calls. Run functions that require some initial setup from the Editor by configuring the Run button. Choose a web site to get translated content where available and see local events and offers.

Scripts are the simplest type of program, since they store commands exactly as you would type them at the command line. Functions provide more flexibility, primarily because you can pass input values and return output values. For example, this function named fact computes the factorial of a number n and returns the result f. 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 order to create a function, however, the user must open the Script Window. If the file contains only function definitions, the first function is the main function, and is the function that MATLAB associates with the file name.

In a function file which contains only function definitions. Note To avoid confusion, use the same name for both the function file and the first function within the file. Simply renaming the function with a. Both scripts and functions allow you to reuse sequences of commands by storing them in program files. Include a local function that defines the integrand,. In that case, the best practice is to use the same name for the function and the file in this example, fact. Often, you store a function in its own file.
