Function Documentation

bool bicgstab	(	const Matrix &	mat,
		const Vector &	rhs,
		Vector &	sol,
		const Precond &	pc,
		uint32_t &	imax,
		double &	eps
	)

BiCGSTAB linear matrix equation solver.

Solves linear matrix equations of form A*X=B.

Returns:

True on success, false on errors

Parameters:

	mat	Matrix on the linear equation
	rhs	Right hand side vector on the linear equation
	sol	Solution vector on the linear equation
	pc	Preconditioner used by the iterator
	imax	Maximum number of iterations to be done in input, number of iterations actually done on output
	eps	Accuracy request for iteration on input, estimated error achieved on output
