Public Member Functions | |
RCholeskyKernel () | |
Default constructor, initializes to 0 size. | |
RCholeskyKernel (LowerMatrixRange< Precision > &A) | |
Seats reference to L, to be factor()'d later. | |
RCholeskyKernel (LowerMatrixRange< Precision > &A, InputStream &in) | |
Constructs from an InputStream, after seating reference to L. | |
void | write (OutputStream &out) const |
Writes to an OutputStream. | |
uint64_t | factor () |
Factors A = L*L'. | |
uint64_t | solveL (const MatrixRange< Precision > &B, char side, char op) const |
Solves op(L)*X=B or X*op(L)=B, overwrites B with X. | |
std::pair< int, int > | inertia () const |
Returns inertia I, (n_plus, n_minus). Useful for schur downdates. | |
int | size () const |
Size inspector. | |
