Detailed Description

template<class T>
class gpstk::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.

Definition at line 408 of file MatrixFunctors.hpp.
