function M = dmult(A,B)
% PURPOSE: computes the product of diag(A) and B
% -----------------------------------------------------
% USAGE:     m = dmult(a,b)
%  where:    a = a matrix
%            b = a matrix
% -----------------------------------------------------
% RETURNS:  m = diag(A) times B
% -----------------------------------------------------             
% NOTE: a Gauss compatability function
