need a help using loop

hello i have this code that i wanted to shorten by using loop but i can't seems to find how

net1 = perceptron;
net1 = train(net1, P, T1);

net2 = perceptron;
net2 = train(net2, P, T2);

net3 = perceptron;
net3 = train(net3, P, T3);

net4 = perceptron;
net4 = train(net4, P, T4);

net5 = perceptron;
net5 = train(net5, P, T5);

when i tried using simple

for X = 1 : 5;
netX = perceptron;
netX = train(netX, P, TX);
end

it will show that T is still an undefined function or variable thank you.

You have learned the hard way one of the first lessons of good programming practice ... don't create a bunch of variables with trailing numbers like T1, T2, T2, etc because it becomes very hard to use them in downstream programming. You are forced to use eval() and the like to get things done, which further obfuscates your code. See this link for good alternatives (like cell arrays):
