Select values from martix with an absolute value and set them to zero.

2 views (last 30 days)
So I'm having trouble with this, my goal is to select values from my random 6x6 matrix (ranging from [-10,10]) with an absolute value of 5 and set them equal to zero.
Any advice, I'm new to Matlab as of recently and don't know what I'm doing half the time.

A = randi([-10 10],6); % 6x6 matrix (ranging from [-10,10])
idx = abs(A) == 5; % Find elements whose absolute value == 5
A(idx) = 0; % Set them to 0
