Load trained neural network using gui in matlab

I am having a trained neural network. I want to load all the variables realed to neural network in the workspace by pressing the pushbutton in gui matlab.

The code is as follows:

function pushbutton5_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton5 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
trained_net_vars = load('netTransfer1');
handles.neural_net = trained_net_vars.net;

The variables are not getting loaded in the workspace. Can anyone help me here !!

Maaz - why do the variables need to be in the workspace? Also, you will need to save the updated handles structure as

function pushbutton5_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton5 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
trained_net_vars = load('netTransfer1');
handles.neural_net = trained_net_vars.net;
guidata(hObject, handles)

to ensure that all other callbacks have access to this object.

I am trying to get the variables in workspace (after loading the neural network) so as to define the variables used in my other push_button.

function pushbutton4_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton4 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
url = 'http://192.168.43.1:8080/shot.jpg ' ; 
filename = 'shot.jpg '; 
a = imread(url) ;
axes(handles.axes1) ;
imshow(a) ;
outfilename = websave(filename, url ); 
tester = imageDatastore(outfilename);
inputSize = evalin('base', 'inputSize');
netTransfer1 = evalin('base', 'netTransfer1');
%tester = imageDatastore('C:\Users\ahmedmaaz20\Desktop\Imo\IMG_20190226_134111.jpg');
tester1 = augmentedImageDatastore(inputSize(1:2),tester);
[YPred1,scores1] = classify(netTransfer1,tester1);

The variables inputSize and netTransfer1 can only be defined if they are in my workspace. A screenshot of my workspace

The above screenshot is the view of my workspace. Here I have already loaded the variables in workspace via command via but instead I want through pushbutton in gui. Hope it helps.

Why can't the GUI set the inputSize and the netTransfer1 variables and hold on to those variables (as fields within the handles structure) within the GUI "workspace"?
