Assume table A:
A = [
'k' 2 4
'a' 3 8
'a' 4 5
'k' 2 2
'a' 3 16
'k' 9 3
'k' 9 8
'a' 4 6
]
If i use sortrows(A) every column is sorted with ascending order:
A = [
'a' 3 8
'a' 3 16
'a' 4 5
'a' 4 6
'k' 2 2
'k' 2 4
'k' 9 3
'k' 9 8
]
Is there a way to sort rows, so first and second column is sorted with ascending order, but third one with descending? I want to get something like this:
A = [
'a' 3 16
'a' 3 8
'a' 4 6
'a' 4 5
'k' 2 4
'k' 2 2
'k' 9 8
'k' 9 3
]

It would likely be necessary to sort each column independently, then concatenate the results into a new matrix.

You can't have a matrix with characters and numbers. But if you convert the characters to double, then:
A=[sort(A(:,1)),sort(A(:,2)),sort(A(:,3),'descend')];
