If you have the 3*1 matrix
C = [345
679
158]
and you want to change it to the 3*3 matrix (or vice versa)
C = [3 4 5
6 7 9
1 5 8]
so that you can for example sort it in descending order of the columns, how would you do this? Thank you.

@Ive J, can you put your Answer down below in the Answers section rather than up here in comments that is used to ask the original poster for clarification? You can also get credit for your answer down there if the poster accepts your answer and/or votes for it.

Ran in:
C = [345
679
158];
D = rem(floor(C ./ [100, 10, 1]), 10)
D = 3×3
3 4 5 6 7 9 1 5 8
