    1          A B C ........................................................
    2          A'B'C'.....
    ...
    31

    ________________
    day1/1hour   A
    day1/2hour   B
    day1/3hour   C
    ..........
    day2/1hour   A'

Hey, no fair asking the same question twice, Dau. It wastes our time when we inadvertently duplicate answers, as I just did here.

If these values A, B, C, etc. as shown are in a 31 x 24 matrix called Mat1, then do:

Mat2 = reshape(Mat1',[],1);
