SU2_LinAlg Namespace Reference

Functions
template<class ScalarType >
void	RegularizePivot (ScalarType &pivot)
	Regularize a pivot that is too small to prevent divide-by-zero, on host and device this needs to clamp to the same value so that the two produce the same factors.
template<class ScalarType >
void	MatrixInverse (unsigned long nVar, ScalarType *matrix, ScalarType *inverse)
	Invert the nVar by nVar dense matrix matrix into inverse via Gauss-Jordan elimination with partial pivoting on the diagonal.

MatrixInverse()

template<class ScalarType >

void SU2_LinAlg::MatrixInverse ( unsigned long  nVar, ScalarType *  matrix, ScalarType *  inverse  )

inline

Invert the nVar by nVar dense matrix matrix into inverse via Gauss-Jordan elimination with partial pivoting on the diagonal.

Note

matrix is used as scratch space and destroyed, inverse must not alias it.

RegularizePivot()

template<class ScalarType >

void SU2_LinAlg::RegularizePivot ( ScalarType &  pivot )

inline

Regularize a pivot that is too small to prevent divide-by-zero, on host and device this needs to clamp to the same value so that the two produce the same factors.
