error: value on right hand side of assignment is undefined |

I have been attempting to run a script that calls a function but I keep
getting the following error: "value on right hand side of assignment is
undefined". The script and function code are shown below respectively.
input = [ 0 0 1;0 1 1;1 0 1;1 1 1];
correct_output = [0;0;1;1];
Weight = 2*rand(1,3) - 1;
for epoch = 1:10000
Weight = SGD_method(Weight, input, correct_output)
endfor
save('Trained_Network.mat')
the function
function SGD_method(Weight, input, correct_output)
alpha = 0.9;
N = 4;
for k = 1:N
transposed_Input = input(k, :)';
d = correct_output(k);
weighted_Sum = Weight*transposed_Input;
output = sigmoid(weighted_Sum);
error = d - output;
delta = output*(1-output)*error;
dWeight = alpha*delta*transposed_Input;
Weight(1) = Weight(1) + dWeight(1);
Weight(2) = Weight(2) + dWeight(2);
Weight(3) = Weight(3) + dWeight(3);
endfor
endfunction
Please provide assistance
Thanks
