SparseCreateSubfactor(_:_:)

Returns an opaque object that represents a subfactor of a factorization of a matrix of double-precision values.

Declaration

func SparseCreateSubfactor(_ subfactor: SparseSubfactor_t, _ Factor: SparseOpaqueFactorization_Double) -> SparseOpaqueSubfactor_Double

Parameters

  • subfactor:

    Defines which subfactor to extract.

  • Factor:

    The factorization to extract the subfactor from.

Return Value

A SparseOpaqueSubfactor_Double structure that represents the subfactor. You must free the resource through a call to SparseCleanup(_:) after you finish with the object.
