Hi,
The functions already exists for different kind of sampling (based on grand)

They also sample from rows/columns

i found this solution, but i'm guessing there must be a more easy and
efficient solution.
not really, may be just a little shorter:
Matrix = [25 ,32 ,40, 50] ;
random = Matrix(grand(1,1,"uin",1,length(Matrix)))
If Matrix is rather of text, length(Matrix) must be replaced with
size(Matrix,"*")

Hi all;
Samuel, I think it will be handy if we have a function which can extract
randomly one, two or more entities of a matrix as well as can also be used
to return a random row/column of a matrix.
Attached you can see a preliminary version of that function.
Regards,
Mehran
