Define filname for exported data with GUI

Hi guys,

I would like to define the name of an exported xls file via GUI, so I added the following commands to a "filename_callback":

contents=cellstr(get(hObject,'String'));

filename=[contents{get(hObject,'String')}];

assignin('base','filename',contents);

in the next step I use the following command to save my Matrix "results":

save('results','filename','xls');

The Excel-file should have the name, that I add in GUI, but I'm always receiving the error: Error using save Variable 'filename' not found.

Does anybody have an advice?

the save command saves the data in .mat format by default. It is not possible to write to xls format with this command, only to ascii if specified by the options. What you are probably looking for is xlswrite

xlswrite(filename,results)

Thanks Ingrid, xlswrite(filename,results) works! Is there a command with which I can define "filename" via GUI. I gues my commands:

contents=cellstr(get(hObject,'String'));

filename=[contents{get(hObject,'String')}];

assignin('base','filename',contents);

are not working, because I can not define the variable "filename" with a word!

[Ingrid]

why not just use

filename = get(hObject,'String');

before calling

xlswrite(filename,results)

I do not see why you want to assign the variable to your base workspace as this is not necessary
