fix Matlab function to load data files with high numbers

There was an issue when data files would reach numbers with three
digits, such as IeFlickering-100.mat. The problem was that it would be
loaded after IeFlickering-10.mat and before IeFlickering-11.mat instead
of being loaded after IeFlickering-99.mat. This is now fixed using
some sorting function.
