Splitting a matrix by even and odd numbers

I have a 200x2 matrix. Column A contains a mixture of even and odd numbers. Column B contains 1s and 0s.
Where the numbers in Column A are even, I need to extract those rows into a new nx2 matrix. The numbers in Column A and B must remain correctly alligned.
Hope you can help!

use rem to determine which list of numbers is even or odd
X = [1 3 4 2 5 4 2] % hint X is the first column of your matrix
iseven = rem(X,2)==0
use this logical vector to select the whole row of M
