general matrix multiplication [message #10999]

All,

I'm looking for a routine to perform generalized matrix multipication
over particular indexes within arrays. For example, let A be a
(10,3,20) array and B be a (20,5,10,30) array. I want to be able to
multiply and add (i.e. matrix multiply) the elemens within index 1,3 of
A and 3,1 of B and produce a result of dimension (3,5,10). While this
can be done simply by using FOR loops, I'm looking for a routine that
does this efficiently, using built-in IDL routines. Does anyone know of
such a routine? ...how I could construct such a routine?

Thanks,

David
