So I want to make a matrix where in the first column I would have even numbers within the range of (32,44] and the second column be odd numbers within that range as well. How would I be able to generate a matrix that would do that besides just putting A=[34 33; 36 35; 38 37; 40 39; 42 41; 44 43].

Thank you very much!

Like this

lower=32;
upper=44;
A=lower+2:2:upper;
B=lower+1:2:upper;
result=[A;B]

This was very helpful and it works when asked for columns! However, I was wondering about rows.

Just do:

result=[A;B]';

Another approach:

v = 32:44;
A2 = (v(rem(v,2) == 1))';
A1 = (v(rem(v,2) == 0))';
A = [A1(2:end) A2]
A =
    34    33
    36    35
    38    37
    40    39
    42    41
    44    43
