Hi,
I have some .mat files generated by an external program which have some variables with a percentage sign in them. Is there any way at all to address these variables within matlab, really just to rename them to something without the special character?
i.e change nnnn% to nnnn
Many thanks

A brute-force, dead-ahead solution is at <Fix .mat file variable names>. It's simply string substitution...as @Walter Roberson notes, the new variable name must be the same length as the original to not corrupt the file; that is you must substitute in a valid character in place of the invalid one, you can't just eliminate it, thereby shortening the name.
