Actually, operator* can be thought of as either an inner product or an outer product. I'm not familiar with the innards of uBLAS, but that is a problem common to most linear algebra libraries.
IIUC in the domain of linear algebra when mathemeticians write AB for 2D matrices A and B, they mean ordinary matrix multiplication (I think inner product) yielding another 2D matrix, and that's what operator* should mean in a linear algebra library. If you want an outer product yielding a 4D matrix I think you're basically outside the domain of linear algebra. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
