Detailed Description
template<typename MatrixType, typename Scalar>
class tngmath::LUBase< MatrixType, Scalar >
provides a LU decomposition. It works on a reference to an existing matrix object. This marix object must exist during the lifetime of the solver object! The documentation for this class was generated from the following file:
- modules/tngmath/tngmath/matharraylu.hpp
