How can I control Matlab from Excel?
(I don't think I have Excel Link.)

My problem is that I have very lage files that I want to process (calculate
mean value etc.). Excel can't handle these large files.

So I want to send filenames one by one to Matlab and in return get the data.
What changes do I need to do in my Matlab program to make i return data?

Best regards,
