ALEXNET TRANSFER LEARNING WITH GUI

Good day everyone, I am Oluwashina. I have been working on AlexNet transfer learning for some week with Matlab R2018a, the console application work very well but doing the same with GUI is reporting errors that I am unable to fix.

Below is the error reported:

Error using classify (line 123)

Requires at least three arguments.

Error in MULTIMODAL_FIGURE>MATCHING_Callback (line 64)

predict = classify(newnet,irisImg);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in MULTIMODAL_FIGURE (line 17)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)MULTIMODAL_FIGURE('MATCHING_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

Please help me, where did I go wrong?

function MATCHING_Callback(hObject, eventdata, handles)
global iris
global face
global newnet
%global predict
clc;
tic;

irisImg = imresize(iris,[227 227]);
%it flag error at "predict = classify(newnet,irisImg);"
predict = classify(newnet,irisImg); 
figure(5)
subplot(1,2,1)
imshow(irisImg)
title(string(predict));
 

faceImg = imresize(face,[227 227]);
predict = classify(newnet,faceImg);
figure(5)
subplot(1,2,2)
imshow(faceImg)
title(string(predict));
 toc;
