Section 8.5 Script Files Versus Function Files

Both script and function files are saved with the same extensions (.m).
The first executable line in a function file must be the function definition line. MATLAB kindly pre-populates the editor window with the expected syntax if you ask to create a new function file.
Variables in a function file are local to the function (their scope is limited to the function) while variables in a script file are recognized in the Command Window.
Script files can use variables defined in the workspace.
Script files are simply sequences of MATLAB commands (statements).
Function files can accept data through input arguments and can return data through arguments.
When a function file is saved, the name of the file should be the same as the name of the function.
