Hey, my program generates a ascii file and i need a save function that can save this file with a name chosen by the user and the extension of the ascii file is always .sin. The user must see a foldermenu (window) where all the files in are viseble.
filemenufcn(gcbf,'FileSaveAs')
doesnt give the right exentension
and
filemenufcn(gcbf,'FileSaveAs','*.sin')
doesnt work either. Thx in advance.

Something like this?
[filename pathname] = uiputfile('*.sin','Save file as');
save(fullfile(pathname,filename),'varname','-ascii')
% or exchange last line with one of the following:
% save(fullfile(pathname,filename),'varname','-ascii','-tabs')
% save(fullfile(pathname,filename),'varname','-ascii','-double')
% save(fullfile(pathname,filename),'varname','-ascii','-double','-tabs')
