gnsstk::LUDecomp< T > Class Template Reference

Detailed Description

template<class T>
class gnsstk::LUDecomp< T >

Performs the lower/upper triangular decomposition of a matrix PA = LU. The results are put into the matricies L, U, and P (pivot), and sign (representing even (positive) or odd (negative) row swaps. LU stores both L and U (all diagonal elements of L are implied 1).
