operating on 3-D arrays [message #8408]

The IDL manual encourages avoiding FOR...NEXT loops by using the vaunted
matrix capabilities of IDL, so I have been trying to handle
three-dimensional arrays with these facilities.

I need to multiply three vectors to produce a three-dimensional array.
One would think that it would suffice to use the matrix multiplication
operator (#) as one does with a pair of vectors to get a two-dimensional
array. However with three vectors, IDL gives the error message

% Operands of matrix multiply have incompatible dimensions...

Anyone have a simple way to manipulate three (and higher) dimensional
arrays in IDL?

Thanks,

John Keck
