i have one problam with PNN, any body help me ..

i'm use matrik 10000*1

在 MATLAB Online 中打开

http://www.mathworks.com/help/toolbox/nnet/ref/newpnn.html

net = newpnn(P,T,spread) takes two or three arguments,
P  R-by-Q matrix of Q input vectors
T  S-by-Q matrix of Q target class vectors

Now look at your input. Your T is something by 3, so that means that Q must be 3 in the above, so your P must also be something by 3. Does your Dataasli array have 3 columns? No, it has 1.

You said specifically that "i'm use matrik 10000*1"

i' m use images with matrix 10000*1, but 1 have 3 images, n when i use it to matlab, my P=[ 10000*3 ], it's true ? n why i'm always have error like this...
