I have a GUI with a uitable with tag uitable1 and I placed some code accessing the figure handle in the uitable1_createFcn

when I run the GUI, it shows me the following error, undefined function or variable figure1 / uitable1

CreateFcn of anything stored with the GUIDE .fig file, execute before the handles structure has been created.

If you want to use CreateFcn to access the handles structure, then you cannot create the object until at least the OpenFcn.

The order that the various CreateFcn execute when loading a .fig is not specified, so do not count on anything else having been created.

What you should probably do is put the relevant code into the OpenFcn, which will not execute until after the CreateFcn have all been executed and the handles structure has been created.

在 MATLAB Online 中打开

At the end of your .m, replace the lines

f = figure1
s = {'Name of Student','Subject','Credits','Mid-I','Mid-II','Mid-III','Best','Assign','Total (Max Marks-40)','Credits scored'}
t = uitable1(f,'ColumnName',s)

with

s = {'Name of Student','Subject','Credits','Mid-I','Mid-II','Mid-III','Best','Assign','Total (Max Marks-40)','Credits scored'}
set(hObject, 'ColumnName', s);
