class uBLASPreconditioner¶

This class specifies the interface for preconditioners for the uBLAS Krylov solver.

uBLASPreconditioner()¶: Constructor

void init(const uBLASMatrix<ublas_sparse_matrix> &P)¶: Initialise preconditioner (sparse matrix)

void init(const uBLASMatrix<ublas_dense_matrix> &P)¶: Initialise preconditioner (dense matrix)

void init(const uBLASLinearOperator &P)¶: Initialise preconditioner (virtual matrix)

void solve(uBLASVector &x, const uBLASVector &b) const = 0¶: Solve linear system (M^-1)Ax = y
