Neural Network error please help me "Inputs and targets have different numbers"

I'm new to Matlab. I've built the code below to classify animals with three inputs in each pattern on the neural network, I'm trying to plot the classification of two inputs after the training phase, but I'm getting an error and I don't know what to do:

net = newp([0 1; 0 1; 0 1],1);
P = [0 0 1; 1 0 1; 0 0 0; 1 1 0; 0 1 1; 1 0 0]'; %three inputs for each pattern
T = [0 1 0 1 0 1]';  %1 = animal is a mammal, 0 = animal is not mammal
net.trainParam.epochs = 2;
net = train(net,P,T);
plotpv(P,T);
plotpc(net.IW{2},net.b{1});

%Tests

NP = [1 1 1; 0 1 0]';
hold on;
plot(NP(1),NP(2)'*r');
Y = sim(net,NP)

P is size [3 x 6] while T is size [6 x 1]. You need to have one T value for each column of P. To fix this, transpose T so its size becomes [1 x 6].

net = train(net,P,T);      %your version
net = train(net,P,T');     %correct version

Thank you!

This approach works with neither the transpose function, nor the T' notation.

Transposing the 2nd input variable does work if it is a column vector with n elements where n is the number of columns of the first input as was the case for the OP's data. But there are other errors with the inputs that transpose would not fix.
