Creating a Preconditioner

init(type: SparsePreconditioner_t, mem: UnsafeMutableRawPointer, apply: (UnsafeMutableRawPointer, CBLAS_TRANSPOSE, DenseMatrix_Double, DenseMatrix_Double) -> Void)

Creates a new double-precision preconditioner.

Inspecting Preconditioner Properties

var apply: (UnsafeMutableRawPointer, CBLAS_TRANSPOSE, DenseMatrix_Double, DenseMatrix_Double) -> Void

A function that should calculate Y = PX, where P is the preconditioner.

var mem: UnsafeMutableRawPointer

The unaltered pointer mem passed as the first parameter of the apply function.

var type: SparsePreconditioner_t

The preconditioner type.
