Another question please:
why when I use MultiplyDivide actor to multiply two matrices (the two provided
by Edward), I cannot use the VectorDisassembler actor? The result of the
multiplication is a vector too, isn't it?
I get the following error message: "ptolemy.actor.TypeConflictException: Type
conflicts occurred in .Build2DMatrix on the following inequalities:
(ptolemy.actor.TypedIOPort {.xxx.Multiply or Divide.output}, general) <=
(ptolemy.actor.TypedIOPort {.xxx.Vector Disassembler.input}, [double])"
Thanks!

Thanks Edwad and Christopher!
@Christopher: actually I found it but I didn't know in which syntax I have to
provide my Matrix/Vector data. It would be very helpful if the documentation of
MuliplyDivide actor includes the example provided by Edward.
Thanks once again!

Muhannad,
The MultiplyDivide actor in Ptolemy does this, see attached.
I'm surprised you could not find this actor in Kepler.
When I entered "Multiply" into "Search Components" and hit "Search" it came
right up.

Sure, just about anything that does multiplication will handle matrices.
MultiplyDivide, Expression, FIR, etc. Math operations are polymorphic.
Matrices are specified in MATLAB syntax in the expression language.
E.g, in the Expression Evaluator:
>> [0, 1;1, 0]*[2; 3]
[3;2]

Hello,
is there any actor that multiplies two arrays? I need to multiply a 2D array
(mXn) with a vector(n).
Thanks!
