This issue has been discussed before and the trouble IIRC is that operator* 
could also mean element-wise matrix multiplication. IMHO the optimal solution 
would be to take over all conventions from Matlab, a convention most are 
familiar with, but the element-wise multiplication operator '.*' can't be 
used in C++ ;( Another suggestion was to defined the element-wise and the 
normal multiplication in a different namespace (I still like this idea very 
much)

Bottomline : last time we found no satisfactory solution ;( but we might take 
it up again.
