How to view confusion matrix of neural network?

I have created it using npr tool. I also want to plot following things of the network.

There were options to view all these plots after training but I did not saved them at that time. How can I see those plots and confusion matrix now.

Mat file is attached in which there is a network I am talking about.

load it and see if you can let me know the things mentioned above.

If you have saved t(=targets), y=(outputs), x(=inputs), net and tr then simply plot:

 % Plots
figure; plotconfusion(t,y);
figure; plotperform(tr);
figure; plottrainstate(tr);
figure; ploterrhist(e);
figure; plotfit(net,x,t);
figure; plotregression(t,y);

Thank you!

With plotconfusion, I am able to see only one confusion matrix. There should be 4 matrices (Training, Validation, Testing, All) like this one:

Hello!

well if you open in your workpace your tr variable there you can find the variables tr.trainInd, for training results , the tr.valInd and tr.testInd . Use them instead of t,y in order to plot whatever kind of data you wish!

Hope this is helpful!

Are there any method to show only alll confusion matrix?
