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

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

A	the matrix (a copy is made if A is not a gmm::csc_matrix)
X	the solution.
B	the right hand side.
rcond_	contains on output an estimate of the condition number of A.
permc_spec	specify the kind of renumbering than SuperLU should do.
