template<unsigned ELEMENT_DIM>

double QuadraticBasisFunction< ELEMENT_DIM >::ComputeBasisFunction	(	const ChastePoint< ELEMENT_DIM > &	rPoint,
		unsigned	basisIndex
	)			[inline, static]

Compute a basis function at a point within an element.

Parameters:

	rPoint	The point at which to compute the basis function. The results are undefined if this is not within the canonical element.
	basisIndex	Which basis function to compute. This is a local index within a canonical element.

Returns:

The value of the basis function.

c_vector< double, ELEMENT_DIM > QuadraticBasisFunction< ELEMENT_DIM >::ComputeBasisFunctionDerivative	(	const ChastePoint< ELEMENT_DIM > &	rPoint,
		unsigned	basisIndex
	)			[inline, static]

Compute the derivative of a basis function at a point within an canonical element.

Parameters:

	rPoint	The point at which to compute the basis function. The results are undefined if this is not within the canonical element.
	basisIndex	Which basis function to compute. This is a local index within a canonical element.

Returns:

The derivative of the basis function. This is a vector (c_vector instance) giving the derivative along each axis.

void QuadraticBasisFunction< ELEMENT_DIM >::ComputeBasisFunctionDerivatives	(	const ChastePoint< ELEMENT_DIM > &	rPoint,
		c_matrix< double, ELEMENT_DIM,(ELEMENT_DIM+1)*(ELEMENT_DIM+2)/2 > &	rReturnValue
	)			[inline, static]

Compute the derivatives of all basis functions at a point within an element.

Parameters:

	rPoint	The point at which to compute the basis functions. The results are undefined if this is not within the canonical element.
	rReturnValue	The derivatives of the basis functions, in local index order. Each column of the matrix gives the derivative along each axis.

		c_vector< double,(ELEMENT_DIM+1)*(ELEMENT_DIM+2)/2 > &	rReturnValue
	)			[inline, static]

Compute all basis functions at a point within an element.

Parameters:

	rPoint	The point at which to compute the basis functions. The results are undefined if this is not within the canonical element.
	rReturnValue	The values of the basis functions, in local index order.

void QuadraticBasisFunction< ELEMENT_DIM >::ComputeTransformedBasisFunctionDerivatives	(	const ChastePoint< ELEMENT_DIM > &	rPoint,
		const c_matrix< double, ELEMENT_DIM, ELEMENT_DIM > &	rInverseJacobian,
		c_matrix< double, ELEMENT_DIM,(ELEMENT_DIM+1)*(ELEMENT_DIM+2)/2 > &	rReturnValue
	)			[inline, static]

Compute the derivatives of all basis functions at a point within an element. This method will transform the results, for use within gaussian quadrature for example.

Parameters:

	rPoint	The point at which to compute the basis functions. The results are undefined if this is not within the canonical element.
	rInverseJacobian	The inverse of the Jacobian matrix mapping the real element into the canonical element.
	rReturnValue	The derivatives of the basis functions, in local index order. Each entry is a vector (VectorDouble instance) giving the derivative along each axis.
