It's not clear. Have you actually created the network yet? If yes, then have you trained it or not?

You haven't explained what type of classifier you have designed. In particular, what is the command sim(T,testimage) supposed to yield?
Please show your code. So far, your explanation is not clear. Your expression for T doesn't look correct.
If you want to display the nearest exemplar of the chosen class, why not just use a nearest exemplar classifier in the first place?

I don't understand how you can be training a net when you don't know what the output should be.
If you have c categories, number them from 1 to c and represent the ith category target by the ith column of the unit matrix eye(c).
Hope this helps.
Thank you for formally accepting my answer
