Hello people,

the problem seems quite simple but I cannot figure out how to implement it.

I have two logical arrays. In one I have several values, and in the other the information about which of them I want to toggle. It is to apply a NOT gate, but I do not know how to implement it.

 A = [1 1 1 1 1
      0 1 0 1 0
      1 1 1 1 1]
 toggle = [0 0 0 0 0
           1 1 1 1 1
           0 0 0 0 0]
 result = [1 1 1 1 1
           1 0 1 0 1
           1 1 1 1 1]

So in the end I want to toggle the middle row of A avoiding the use of if statements. How to do it?

Thanks!

A = [1 1 1 1 1
    0 1 0 1 0
    1 1 1 1 1] 
toggle = logical([0 0 0 0 0
         1 1 1 1 1
         0 0 0 0 0])
% Apply not(), which is equivalent to ~
A(toggle) = ~A(toggle)
