How I can sort matrix according to both the first row and the third row as in the example?

Question

How I can sort M according to both the first row and the third row as in the following example:

M = [25 30 34 25 25 50 30 34
      3  4  8 11 99 58  3  4
     45 25 11 63 55 41 28 44]

the desired result:

Ms = [25 25 25 30 30 34 34 50
       3 99 11  4  3  8  4 58
      45 55 63 25 28 11 44 41]

Answer 1

You can use sortrows and just transpose twice (i.e. before and after) to effectively make it a "sortcolumns":

Ms = sortrows(M',[1,3])'
