Thanks for the pointer.  The C++ trick that lets you do

   M (0, 0) = ...

escapes me.  I presume the SparseComplexMatrix has some form of operator
overloading that handles things in a clever way.  So if I want to access
the (i,j) matrix element, is it simply

  std::complex<double> val;
  val = M(i,j);

or is it more complicated?
