The error with your employed fcn called net() that is not defined as a function and considered in your code as a variable. Thus, define the fcn net() first using function file or anonymous fcn and then call it within a loop.

I have load the .mat file into the script can i know why it still show the same error

below is my script

storedStructure = load('test2.mat');
net = storedStructure.net;
for i=1:Ne
    segImage=reshape(double(imread(fullfile('segmentedImages', sprintf('image%d.png', i)))) , 784, 1);
    outputMatrix = net(segImage);
    row=find(ismember(outputMatrix, max(outputMatrix(:)))); % returns the row number which has highest probability
     figure(i);
     colormap(gray)
    character = double(imread(fullfile('segmentedImages', sprintf('image%d.png', i))));
     imagesc(~character)
     title(imageLabeler(row))
    detectedWord(1,i)=imageLabeler(row);
end
