I have a 12 x 12 matrix and I have used the command 'sortrows' to sort the matrix in ascending order of rows. How can I do the same but sorting by columns (i.e. ascending order of columns) instead of rows?

Ran in:
I would suggest transposing your matrix, sortrows, then transpose the result.
A=rand(5)
A = 5×5
0.2220 0.3790 0.0549 0.6643 0.6145 0.0431 0.4532 0.5809 0.2667 0.4518 0.7695 0.6946 0.0495 0.6197 0.7591 0.7629 0.7669 0.7549 0.9592 0.4810 0.3152 0.3356 0.0617 0.1093 0.6415
B=sortrows(A')'
B = 5×5
0.0549 0.2220 0.3790 0.6145 0.6643 0.5809 0.0431 0.4532 0.4518 0.2667 0.0495 0.7695 0.6946 0.7591 0.6197 0.7549 0.7629 0.7669 0.4810 0.9592 0.0617 0.3152 0.3356 0.6415 0.1093

Thank you very much! I used sortrow on the transposed matrix and figured it just didnt work. Didn't think to transpose that as well, makes sense.
