Hi Muhannad,
It would probably be best if you wrote a Java actor that did such an
operation.
The Ptolemy II expression language includes a sort() operation that
works on numeric ArrayTokens (except for complex).
The Interpolator and Pulse actors are close to what you want, but the
index parameter must be increasing in value and the index parameter is a
parameter, not a PortParameter.
The way I would approach this is to create a new actor that read in two
tokens, A1 and A2, from ports, performed the operation and created a new
token and outputted the new token.

Hello,
is there any way to sort a multi-dimensional array according to some column,
e.g. sort(A, j). Or if I have two one-dimensional arrays A1, A2 and after
sorting A1, I need that A2's elements that correspond to A1's ones have the
updated indices like A1.
Example:
A1 = {2, 0, 3, 1}
A2 = {"x2", "x0", "x3", "x1"}
After sorting A1 (say descending), I need that A2 looks like that: A2={"x3", "x2", "x1",
"x0"}
Thanks!
Best regards,
Muhannad
