Workspace variables into functions

Reading multiple variables into a function and saving those variables in a loop

Problem definition:

This code is to help beginners to understand how reading multiple variables into a function and storing them within a loop without using 'eval' function. This is more of a tutorial code than a specific one.

I have multiple variables (X1,X2,X3,...,X10) stored in a mat file, i.e. WS1.mat, which to be read into a function i.e. myfunc and after the expressions are calculated, I want
to store them in seperate variables, (A1,A2,A3,...,A10). I want those variables to be %stored in 'base' workspace, instead of 'function' workspace
