Re: [eigen] Obtaining triplets from sparsematrix

Another thing, the example should be changed from
SparseMatrix<double>::InnerIterator
to
typename SparseMatrix<double>::InnerIterator
at least that's what gcc says.

not in this case, only if you write typename SparseMatrix<Scalar>::InnerIterator with Scalar a template typename.
Correct.
Why is this rule necessary? When should we use typename?
