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 that case, the best practice is to use the same name for the function and the file in this example, fact. You can call the function from the command line, using the same syntax rules that apply to functions installed with MATLAB. For instances, calculate the factorial of 5. Starting in Rb, another option for storing functions is to include them at the end of a script file. For instance, create a file named mystats. The script calculates the permutation of 3,2. Call the script from the command line. The first line of every function is the definition statement, which includes the following elements.

A function is a group of statements that together perform a task. The name of the file and of the function should be the same. Functions operate on variables within their own workspace, which is also called the local workspace , separate from the workspace you access at the MATLAB command prompt which is called the base workspace. Functions can accept more than one input arguments and may return more than one output arguments. The following function named mymax should be written in a file named mymax. It takes five numbers as argument and returns the maximum of the numbers. The first line of a function starts with the keyword function.

For example, find the first integer n for which factorial n is a digit number:. It is a good idea to indent the loops for readability, especially when they are nested that is, when one loop contains another loop :. You can programmatically exit a loop using a break statement, or skip to the next iteration of a loop using a continue statement.
