% Testing script
load('Trained_Network.mat');
input = [ 0 0 1;
0 1 1;
1 0 1;
1 1 1;
];
N = 4;
for k = 1:N
transposed_Input = input(k, :)';
weighted_Sum = Weight*transposed_Input;
output = Sigmoid(weighted_Sum)
end

Which is to say, that the testing script had no disp() or fprintf(), and that every line in the script that could potentially return a result had the result supressed with the semi-colon .
