I have written the following code % writing into the workspace Table = zeros(5,3); A = 1:5; c = d(i); m = 1; for i = 1:length(A) y1 = c; % c = hiddenLayerSize; y2 = performance; x = ? %value of epochs where the best validation occurred y = [y1 x y2]; Table(m,1:3) = y; m = m + 1; end please, what code will get the Epoch out. see the attached.

在 MATLAB Online 中打开

The training record TR contains the complete time history of all 3 subsets.

 [ net tr ] = train( net,input,target);
 tr = tr    % no semicolon

Also check the documentation

 help tr
 doc tr

Hope this helps.

Thank you for formally accepting my answer

thanks it actually helped me to get to where am going. the code I used to achieve my goal is this: x = getfield(tr,'best_epoch') Now my next challenge is to get the time corresponding to this epoch. kindly assist. thanks once again
