Hello, 1. How do I linearize Linearize variable A that should go from a MxN array to a (M*N)x1 column vector. The new (M*N)x1 vector should be calculated by going down the columns of "A".
2. How do I take the top half of the array i.e. all of the columns and the first half of the rows assuming that there are an even number of rows.
3. How do I create a mask where B is equal to 0?
Thank You.

1. A(:)
2. A(1:(M/2), :);
3. What is B? How about B = zeros(size(A));
Did I just do your homework???

You said A is a "MxN" array. I would think you should know what M is. It's the number of rows.
