SIGMOID FUNCTION

function y = Sigmoid(x)
y = 1/(1 + exp(-x));
end

SGD Method function

function Weight = 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);
end
end

Training script

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);
end
save('Trained_Network.mat')

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 .
