Hi,

I have a GUI that has 25 checkboxes to plot different signals in an axes. There are several operations that can be performed by the user on the signals by triggering callbacks (scaling,rotation,...).

I just want to re-trigger the 25 callbacks without having to copy the 25 callback calls. Is there any way of doing this using regular expressions (with regexp or similar)?

Jose

No.

Create a cell array of handles to the functions, and then you can loop through that.

You should also be considering using the same function for all of them, possibly with different parameters or by looking at the Tag of hObject to figure out which button was invoked.
