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.
So, why not issuing a DeprecationWarning on a matrixmultiply function use?
