How can I load the .mat file in GUI?

I have train alexnet and save it into .matfile. when I load that file to classify an image it is working fine like this

clear all;
clc;
load all.mat;
[FileName,PathName] = uigetfile('C:\Users\NH529\MATLAB\Deep learning\Images\*.jpg');
I = (imread([PathName '\' FileName]));
I=imresize(I, [227 227]);
label = classify(myNet,I);
finallabel=categorical(label);
imshow(I),title(sprintf('%s', finallabel));

But when I load this .matfile in the GUI it is giving me an error. How can I load it into GUI file. I have searched and tried the available answers but they didn't work

How can I solve this problem? Please help me

You load the data from the .mat file into a variable named myNet. But then you do not do anything with this variable. In particular, you do not pass it to whatever functions need to use it.

Solution: pass that variable.

Tip: if you want to write better code then get rid of the global variables too.

I have used this variable in classification. The code where I used this variable is as

%
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
label = classify(myNet,I);
finallabel=categorical(label);
textLabel = sprintf('Image Class = %s', finallabel);
set(handles.label, 'String', textLabel);

"I have used this variable in classification. The code where I used this variable is as"

Nope, because you never pass that variable to that function. It does not exist inside the workspace of pushbutton2_Callback because you have not passed that variable to that workspace.

I would recommend that you use nested functions or guidata. Read more here:

You will find many threads on this topic, with complete working example. Just search this forum.
