Re: convert double to complex

Hi Peter,

using 
  mtl::copy(GSM, GSMcomplex);
with
  typedef mtl::matrix< complex<double> , symmetric<lower>, envelope<>, row_major >::type ComplexEnvelopeMatrix;
  typedef mtl::matrix< float_type, symmetric<lower>, envelope<>, row_major >::type EnvelopeMatrix;


I get this message...
