For loop is not working

I started with matlab for neural networks but when i use for loop, it would only return me the output for last element

code is:

load('Trained_network.mat');

N=3;

for i = 1:N

transposed_Input = input(i,:)';

weighted_sum=Weight*transposed_Input;

output=sigmoid(weighted_sum);

end

It returns output only for Nth element while It should return for 1:N

A loop runs the same code over and over. That means you overwrite your variables each time. As you've written it, the result will only be the value of output from the final loop. If you want to capture the results from each loop, use indexing.

for a = 1:5
    output(a) = a;
end

The final value of output in this example is

output =

     1     2     3     4     5
