[eigen] Is post-multiplication by diagonal matrix optimized?

[Manoj Rajagopalan <rmanoj@xxxxxxxxx>]

Hi,

   I've been told that premultiplication by a diagonal matrix is optimized by 
eigen:

VectorXd v(N);
MatrixXd M(N,N);
v.asDiagonal() * M

  Is M * v.asDiagonal() also recognized and optimized?

thanks,
Manoj
