Date
August 2004. We do not use gmm_superlu_interface.h for a good reason. This file does not include any of the superlu headers, hence when getfem is installed, it does not need to install the superlu headers.

Function Documentation

◆ SuperLU_solve()

template<typename MAT , typename V1 , typename V2 >
int gmm::SuperLU_solve ( const MAT &  A,
const V1 &  X,
const V2 &  B,
double &  rcond_,
int  permc_spec = 3 
)

solve a sparse linear system AX=B (float, double, complex<float> or complex<double>) via SuperLU.

Parameters
Athe matrix (a copy is made if A is not a gmm::csc_matrix)
Xthe solution.
Bthe right hand side.
rcond_contains on output an estimate of the condition number of A.
permc_specspecify the kind of renumbering than SuperLU should do.
