Matrix Multiplication

[nonathecoda]

I'm trying to implement a Kalman Filter in Gama, which is why I need to multiply matrices. However the "*" operator only seems to multiply matrices value by value. Is there any way I can multiply two matrices, like e.g. a 2x3 with a 3x1 matrix?

Thanks!

Dear, you have the . operator that does the job (not well documented I admit :-) ). See below : write matrix([[1],[2]]) . matrix([[1,3]]);

…

---> 7 write matrix([[1,3]]) . matrix([[1],[2]]);
