how to remove the error? Too many output arguments. Error in nn1 (line 118) [x t] = featureVector; how to remove the error?

featurevector is of size 3*20(extracted H,S,V values for 20 images)

t=ones(1,20 ); 
[x t] = featureVector ; 
net = patternnet(10 ); 
net = train(net,x,t ); 
view(net ) 
y = net(x ); 
perf = perform(net,t,y ); 
classes = vec2ind(y );

If Featurevector is a matrix/ data..this line is not correct:

[x t] = featureVector ;

What you want to do in the above line?

Since we have no idea what you intended to do with that line, how can we tell you to change it?
