Link to original bugzilla bug (#885)
Version: 3.3 (current stable)
Description
This causes things like the following not to compile:
template<class Derived>
void foo(const Eigen::MatrixBase<Derived>& ) {}
int main() {
Eigen::MatrixXd A;
foo(A.triangularView<Eigen::Upper>()); }
Also, these classes miss some useful functions, like isZero(), or sum().
