[scilab-Users] gsort function

[Mathieu Dubois]

Hello,

Do you want to sort every column (in its own order)? If so I think you 
should use gsort(D, 'c').

If you just want to sort 1 column you could use gsort(D(:, j), 'c').

Last but not least you can sort one column (as above) and use the vector 
k (return by gsort) to permute the other columns (so each row is preserved).

HTH,
Mathieu
