Gunter,
thanks so much for all your trouble. Unfortunately, we seem to be using
different version of boost/ublas. My
generalized_vector_of_vector< double, row_major,
vector<compressed_vector<double> > > doesn't seem to have nnz():
error C2039: 'nnz' : is not a member of
'boost::numeric::ublas::generalized_vector_of_vector<T,L,A>'
I also tried to compile your example program with g++/Cygwin:
$ g++ -I /cygdrive/d/dev/boost -D NDEBUG -O2 sparse_fill3.cpp -o sparse_fill3
sparse_fill3.cpp: In function `int main(int, char**)':
