 What is an array, cell, structure, string?

No idea really what you're trying to ask for first one, sorry...but try the "Getting Started" tutorial page...

For the latter, see matlab data-types

There are no different ways to create MAT files, but only one way: the save command. See:

doc save

There is no specific object called "structure" in Matlab, but "struct":

doc struct

You can search in the documentation also by:

docsearch struct

The basics are explained in the "Getting Started" chapters of the documentation and e.g. in Matlab's free "Onramp" tutorial: https://matlabacademy.mathworks.com/

It is more efficient to learn the basics from tutorials than to ask them in the forum.
