I created my own structure array under a pushbutton so that I could store a lot of data collected in an organized manner. I tried referencing this structure in a subsequent pushbutton, but received an error "undefined function or variable".

Does anyone know if I can reference my own structure array throughout the GUI?
Do I need to reference it through handles?
Is there an easier way to do this through handles alone?

Here's a sample of some of the code:

PS(1).TLP = [fA, Ph, fFr, DF, Fr, Ds];
PS(1).Bm= [fKa, Dk, fDt, fFa];                                          
PS(1).sp = [fp, fk, nPSe, A2, A1, A0, ScK];  
This goes on and on..

Thanks!

Just add your structure to 'handles' as follows

handles.PS = PS;
guidata( hObject, handles )

then you can access it in any callback that has handles as

handles.PS

As for the question if it is easier through handles alone: No, not really. Having your own structure attached to handles is neater than piling a vast amount of raw data onto the handles struct.
