h = figure;

set(h,'KeyPressFcn',@KeyDownCb,'KeyReleaseFcn',@KeyUpCb)

tic;

function KeyDownCb(~,evnt)

       out = sprintf('Key: %s\n',evnt.Key);

     disp(out)

        x1=toc;      
     f=x1-x2;

         disp(f)

end

    function KeyUpCb(~,evnt)

         x2=toc;

you will need to call the function save() in the pushbutton callback. The documentation for save() will give you a good explanation of how to do this.

[puja dutta]

i tried but i am not gettin.i used

savefile='puja.mat';

save(savefile,'handles.f')

in pushbutton but it shows error

handles.f is not a variable name

[Joseph Cheng]

when you put a break point before the save does handles.f exist?

if not when you create handles.f you will need to call guidata(hObject, handles); at the end of the function (before it goes back to the main gui section) to update the handles object.

or... possibly that maynot work... i just noticed that you're not using guide.
