Description Benoit Jacob 2010-10-16 04:58:23 UTC
There are still room for better vectorization, e.g., v0.asDiagonal() * v1 is not vectorized while it is simply v0.cwiseProduct(v1);
Comment 1 Gael Guennebaud 2013-06-18 17:46:36 UTC
Its better now:

Summary:     Bug 71: enable vectorization of diagonal products in more cases.

but I think we can even do better with matrices, so let's keep it open.
Comment 2 Gael Guennebaud 2013-06-18 18:57:57 UTC
OK, the problem with matrices is much more general, so let's close this one and start another one.
