Member Function Documentation

template<typename T>

void ChLagrangeBasis1D< T >::PrintParam

(

)

[inline, virtual]

Prints the name of the basis and its size.

Reimplemented from ExpansionBasis1D< T >.

template<typename T>

void ChLagrangeBasis1D< T >::compute	(	T	xi,
		T *	val
	)			[inline, virtual]

The basis functions: Computes the values of all the basis functions at a given point and stores the values in the array T val [N].

Parameters:

[in]	xi	The argument (should be in )
[in]	val	N values of the basis functions at 'xi'

Implements ExpansionBasis1D< T >.

template<typename T>

void ChLagrangeBasis1D< T >::ComputeExpansion	(	KernelExpansion1D< T > &	k_expansion,
		ChLagrangeBasis1D< T > &	Phi,
		ChLagrangeBasis1D< T > &	Psi
	)			[inline, static]

Computes the expansion of the kernel (initializes the references to the bases and computes the coefficients).

Parameters:

[in]	k_expansion	The kernel
[in]	Phi	The x-basis
[in]	Psi	The y-basis

Note:

'Phi' and 'Psi' may reference the same object.
