The "basic" linear algebra functions like matrix*matrix, matrix*vector
etc are done in a separate "BLAS" (Basic Linear Algebra Subprograms)
library. The naming convention is confusing since I believe its
from the old fortran conventions, but the "mv" means matrix*vector.
The "d" means double precision and I don't off hand know what the ge
means, but you can read the blas docs for more info.
