Hi Guys!

I have a figure containing a listbox and pushbutton. What i want is that on opening the GUI, the listbox string sets to some matrix stored in the same directory. I put some commands in the figure opening function, but could not get the desired results. In short , am unable to call the listbox object from the figure opening function.

Thanks in advance..

Assuming your are using GUIDE, which it sounds like you are, you should be able to simply call the listbox by the tag you gave it in the .fig file and then do whatever you want with it.

e.g.

handles.listbox1.String = ...
