How to remove some values in a matrix?

Hello,

For example I have a matrix

[66 62;
 64 70;
62  100];

In the first column, I just want keep those values between 60 and 65, in the second column, I want to keep the values between 61 and 70, if not those case, I want to delete those rows. namely the new matrix will be [64 70];

mask = A(:,1) >= 60 & A(:,1) <= 65 & A(:,2) >= 61 & A(:,2) <= 70;
B = A(mask,:);
