Finding duplicate variables in multiple M files

I am working on a legacy program and have inherited a number of m files that are used for defining parameters in our Simulink models. I want to scan the files to see if there are duplicates or places where a variable is defined multiple times. Is there a simple way to do that?

Thanks!

Run each M-file and save a .mat file afterwards (don't forget to run "clear" first each time)

VarList1=fieldnames(load('MFile1.mat')) will give you the variable list in M-file 1.

Use intersect(VarList1, VarList2) to find common variables.
