Member Function Documentation

void MinusMatrix::MultV	(	UserVector< double > &	y,
		const UserVector< double > &	x
	)			const [inline, virtual]

Computes the product of this matrix with a dvector.

Parameters:

	y	The dvector to store the result in: y = - A*x.
	x	The dvector to multiply with the matrix.

Implements UserMatrix.
