Detailed Description
template<typename T>
class NOX::LAPACK::Matrix< T >
A simple square matrix class for use by NOX::LAPACK::Group.
The matrix is stored as a vector<T> array. It is templated so it can store entries of different types. For example, the LOCA LAPACK group stores a complex matrix for Hopf tracking.
