Hi guys,
I call my input data with the following line:
[fileName,pathName] = uigetfile('H:\inputdata\*.txt');

and do different calculation on th data set and at the end I save the result in excel files with xlswrite command. 

xlswrite( fileName, A)  % is the the result of a certain calculation
 and 
xlswrite( fileName, B)  % is the the result of another  calculation on the same file

when save the files in excel I want to add the the "A" and "B"  to file name, then I know that which file contains what result.
 
can you tell me how I can do that?
cheers
