Thanks, Bruce. I was looking in the tutorials and it was not clear the
working procedure of the where function (it is now?). It works on a mask
right? So if have result = where(xy) it would mean that xy is a matrix (in
the case 2-D) where de elements of the roi have value 1 and the others have
value 0.
So maybe the solution is seeking for i,j such that xy(i,j) eq 1. If true
then adding these (i,j) to a pointer and returning this two-dimensional
array? What do you say? I'm going to try.
Cheers,
Nuno.
