Matrix Multiplication

Hi Rapid Miners,

How can I do matrix multiplication in RM? Suppose that I have two examplesets, A and B.

A has 5 rows and 3 attributes.
B has 3 rows and 4 attributes.

Both A and B have numerical values. Assuming A and B as two matrices, which operators or combination of operators will let me to do a matrix multiplication of A*B?

Thanks,
Shubha Karanth.

RM does matrix multiplication with the JAMA library ( q.v at http://math.nist.gov/javanumerics/jama/ ), so the answer is none.

How can I install that library? I can't find it on the marketplace...
