gsort function

[Carrico, Paul]

Dear all,

 

Sort algorithms are rather new for me ...

 

In the example herebellow and after some tests, I've noticed that the
matrix is sorted from the 1rst column :

- is it possible to choose the column to sort ?

- otherwise does it mean it's necessary to permute the desired column
with the first one to sort ?

 

Thanks in advance

 

Cheers

 

Paul
