For the matrix multiplication or array dot, you use BLAS3 functions as they are more or less the same. For the rest, nothing inside Numpy uses BLAS or LAPACK explicitelly IIRC. You have to do the calls yourself.

And does numpy/scipy just then automatically use them? When I do a matrix
multiply, for example?
