It's true that matrixmultiply has been deprecated for some time (at
least 8 years...) The basic dot function gets over-written with a
BLAS-optimized version but the matrixmultiply does not get changed. So
replace matrixmultiply with dot. It wasn't an intentional thing, but
perhaps it will finally encourage people to always use dot.
