Bit confused about this.

Surely pre- and post-multiplication …

This patch primarily moves the code for the Cholesky decomposition up to the "matrix double dense" module, where it belongs, and is consistent with the approach for other decompositions. The SciPy …
This is not the correct place for this question, but as this project has no mailing list, I don't know where else to post it.
I need to factor some rather large matrices (300,000 examples and 30,000 …
