How to view the Scores?

Hello,

I used this code:

[C, scores] = semanticseg(paviaU(100:100+255,1:256,20:25), net);

[GN, ~, G] = unique(C);

G = reshape(G,256,256);

I now want to check if the categories are good but I do not remeber the code/s that are used to view it. I think its something like:

C (1)

I am most likely wrong about that. Could you please inform me on the code/s that I need to use?

Thanks
