indeed, thanks.

BTW, the MKL version is now consistently more accurate than Eigen without MKL.
Could be a hint on the usage of FMA, but I'm just guessing.

It's more likely more accuracy in the lowest eigenvalues as we assume that eigenvalues lower than machine_epsilon * largest_eigenvalues are zero.
