Detailed Description

template<class T>
class gmm::SuperLU_factor< T >

◆ solve()

template<class T >
template<typename VECTX , typename VECTB >
void gmm::SuperLU_factor< T >::solve ( const VECTX &  X,
const VECTB &  B,
int  transp = LU_NOTRANSP 
) const
inline

After factorization, do the triangular solves.

transp = LU_NOTRANSP -> solves Ax = B transp = LU_TRANSP -> solves A'x = B transp = LU_CONJUGATED -> solves conj(A)X = B
