GUI help

[dbdb]

Hi,

I'm trying to load data from a MAT file into my M file when creating a GUI.

Is there a way to access the variable names and print them on the screen??

I've used 'load('filename', 'X', 'Y', 'Z')' command but you seem to need to know the actual variable name.

The code is:

--------------------------------------------------------------------------------------------------------------

function OpenFile_Callback(hObject, eventdata, handles)

global X Y Z A B C Q l Leds_1_6 Time MetrisFileInfo

[newfile,newpath]=uigetfile('*.mat','Open File...')

fid=[newpath,newfile];

load(fid)

l=length(Leds_1_6)

%************************************************************

%* PLOT

function Plot_Callback(hObject, eventdata, handles)

global X Y Z A B C l Leds_1_6 Time MetrisFileInfo

if get(handles.X,'Value')

plot(Leds_1_6(1,2:l))

title('Plot of X Values');

---------------------------------------------------------------------------------

The variables of the MAT file being Leds_1_6, Time and MetrisFileInfo. The class of the variables is double, double and char respectively.

I want to be able to open other MAT files which will have different variable names..

Any ideas??

Thanks!
