MATLAB: Accessing Path names for reading Excel and saving .mat files in same folder

Question

Hi,

I have Excel data files in a number of folders under the MATLAB folder (all on the MATLAB path). To speed up analysis, I would like to only read the Excel file once, and then save the variables in a .mat file *in the same folder *as the original Excel file.

How do you get the actual path name for the Excel file without having to manually input it so it can be prepended to the .mat file name?

Thanks

Doug

Together with:

idx = find(TheFilename == '.', 1, 'last');
NewFilename = TheFilename;
NewFilename(idx:end) = '.mat';
