friend

C= A*alpha.

note: only active DOF are multiplied, others are just copied note: the user is responsible to delete the newly created matrix C

TSquareMatrix2D& operator*	(	const double	alpha,
		const TSquareMatrix2D &	A
	)

friend

C= A*alpha.

Same as TSquareMatrix2D& operator+(const TSquareMatrix2D & A, const TSquareMatrix2D & B);

note: only active DOF are multiplied, others are just copied note: the user is responsible to delete the newly created matrix C

double* operator*	(	const TSquareMatrix2D &	A,
		const double *	x
	)

friend

y= A*x

note: only active DOF are multiplied, others are just copied from x

TSquareMatrix2D& operator+	(	const TSquareMatrix2D &	A,
		const TSquareMatrix2D &	B
	)

friend

add to matrices A and B

note: only active DOF are added note: only works for matrices with the same sparsity pattern
