I am using Neural Networks Toolbox. It allows me to plot confusion Chart by using "plotconfusion" command. But it does not allows me to see confusion matrix in the workspace. I tried to use "confusionchart" command but it pops up an error.
Error: Error using confusionchart (line 64)
Expected m to be a square matrix.
I have also attached both matrices of Targets and Outputs.
Where,
"t.mat" is a Target Matrix and "y.mat" is an output Matrix.

You need to use the function confusionmat
actual = t;
predicted = y;
mat = confusionmat(actual,predicted);
