Use the training record tr from [ net tr ] = train(net,x,t) to find the separate sets of tr/val/tst indices. From these you can use plot confusion to get the 3 separate confusion matrices.
You may want to take a good look at those matrices to see which classes never get confused with each other. Then you may be able to use plotconfusion to obtain several submatrices that simplify the understanding of the misclassifications.
Hope this helps.
Thank you for formally accepting my answer
Greg
