[kepler-users] Sort Multidimensional Array

[Christopher Brooks]

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.
