Member Function Documentation

void AdiniPoly::compute	(	const Point< 2 > &	unit_point,
		std::vector< double > &	values,
		std::vector< Tensor< 1, 2 > > &	grads,
		std::vector< Tensor< 2, 2 > > &	grad_grads
	)			const

Computes the value and the first and second derivatives of each polynomial at unit_point.

The size of the vectors must either be equal 0 or equal n(). In the first case, the function will not compute these values, i.e. you indicate what you want to have computed by resizing those vectors which you want filled.

If you need values or derivatives of all polynomials then use this function, rather than using any of the compute_value(), compute_grad() or compute_grad_grad() functions, see below, in a loop over all polynomials.

double AdiniPoly::compute_value	(	const unsigned int	i,
		const Point< 2 > &	p
	)			const

Computes the value of the ith polynomial at unit_point.

Consider using compute() instead.

Tensor< 1, 2 > AdiniPoly::compute_grad	(	const unsigned int	i,
		const Point< 2 > &	p
	)			const

Computes the gradient of the ith polynomial at unit_point.

Consider using compute() instead.

Tensor< 2, 2 > AdiniPoly::compute_grad_grad	(	const unsigned int	i,
		const Point< 2 > &	p
	)			const

Computes the second derivative (grad_grad) of the ith polynomial at unit_point.

Consider using compute() instead.

Tensor< 2, 2 > AdiniPoly::compute_grad_grad_2	(	const unsigned int	i,
		const Point< 2 > &	p
	)			const
