mtimes

   Product of a GMixture and a constant/GMixture.

   Returns the Gaussian mixutre resulting from multiplying the two input
   parameters. Those can be two Gaussian mixtures or a Gaussian mixture
   and double. In this second case the weigths of the mixture get scaled.

0002 %   Product of a GMixture and a constant/GMixture.

0004 %   Returns the Gaussian mixutre resulting from multiplying the two input
0005 %   parameters. Those can be two Gaussian mixtures or a Gaussian mixture
0006 %   and double. In this second case the weigths of the mixture get scaled.
