Creating a matrix (B)of the same size as matrix (A), containing only even/odd values

First time poster here, with something that should be simple for most...

I am needing to:

1. Create a 6x6 magic matrix (A)

2. Create a matrix of the same size, which displays all the even numbers, and displays the rest as zero.

3. Create a matrix of the same size, which displays all the odd numbers, and displays the rest as zero.

I've figured out how to extract the even/odd numbers and put them into a vector, but not a new matrix.

For this I am using:

Evens: A1=A(~mod(A,2))

Odds: A2=A(mod(A,2))

I am guessing there is a similar technique for creating a matrix, but the concept is currently lost on me.

Any help would be greatly appreciated!

Close, but try it with multiplying by a mask:

A = magic(6)
evens = ~mod(A,2)
odds = mod(A,2)
Aevens = A .* evens
Aodds = A .* odds
