I get a compilation error when trying to do a substraction of a complex 
matrix on a double matrix. I can of course do

matrix< double > rm;
matrix< std::complex< double > > cm;
matrix< std::complex< double > > result = matrix< complex >( rm ) - cm ;

but I guess I'm loosing efficienty here creating the temporary complex matrix 
out of rm ?
