Inheritance diagram for hp2D::KarniadakisDeriv2:

Public Member Functions
	KarniadakisDeriv2 (const int P, const Real *xP, const int NxP, const bool cache=true)

	~KarniadakisDeriv2 ()
	Copy constructor.

uint	n () const
	Returns the number of shape functions.

uint	nP () const

const Real *	values () const
	Returns the values of the shape functions.

Protected Member Functions
virtual std::ostream &	info (std::ostream &os) const
	Returns information in an output stream.

Protected Attributes
Real *	values_
	Values of the shape functions.

Detailed Description

Part of the multidimensional expansion bases for the shape functions of Karniadakis and Sherwin. Computes the derivate of $\psi^a_i(x)$ . In difference to Karniadakis<1,1> the first function is left out, so that the shape functions are linearly independent.

The first functions are: $\psi_0 = \frac{1}{2}$ , $\psi_1 = -x\frac{1}{2}$ , $\psi_1 = (-3x^2+1)\frac{1}{2}$ , $\psi_2 = \frac{3}{4}x(5x^2-3)$ /
