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.
