Hi,

I'm wondering what is the best way of initializing a 4x4 matrix. I'm currently using the comma initializer, but it shows up quite high on a valgrind profile compared to taking the inverse of the same matrix or preprocessing the coeffs (pow, ln...)..

I'm using Eigen 3.2.4, but I can upgrade.

Cheers,

Matthieu
