[kepler-users] Arrays Multiplication

[Ali, Muhannad]

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!
