Detailed Description

implements a permuted matrix, e.g., P·A·R

For a given, general matrix A and two permutations R, P, the product $P \cdot A \cdot R$ is represented. If P/R is nullptr, it is treated as identity.

virtual void apply	(	const TVector *	x,
		TVector *	y,
		const matop_t	op = `MATOP_NORM`
	)		const

virtual

mapping function of linear operator $A$ , e.g. $ y := A(x)$ . Depending on op, either $A$ , $A^T$ or $A^H$ is applied.

Implements TLinearOperator.

virtual void apply_add	(	const real	alpha,
		const TVector *	x,
		TVector *	y,
		const matop_t	op = `MATOP_NORM`
	)		const

virtual

mapping function with update: $y := y + \alpha A(x)$ . Depending on op, either $A$ , $A^T$ or $A^H$ is applied.

Implements TLinearOperator.
