see http://advice.mechanicalkern.com/question/10/whats-the-difference-between-numpylinalg-and-scipylinalg

The only way, to find out which lapack/blas routines are used, is to
go through the functions (docs or source), at least from what I have
seen. (e.g linalg.lstsq call different lapack functions, but even
reading the help for the lapack functions it didn't become clear to me
what the real difference in the calculation method is.)

Cheers,

Josef
