Detailed Description

template<typename ValueType>
class Fiber::ConstantScalarShapeset< ValueType >

A shapeset containing only one function: the constant function.

Member Function Documentation

template<typename ValueType>

virtual void Fiber::ConstantScalarShapeset< ValueType >::evaluate ( size_t  what, const arma::Mat< CoordinateType > &  points, LocalDofIndex  localDofIndex, BasisData< ValueType > &  data  ) const

inlinevirtual

Evaluate the shape functions making up this shapeset and/or their derivatives at specified points.

Parameters

[in]	what	Bitwise combination of zero or more flags defined as members of the BasisDataType enum. Specifies what shall be evaluated: the values of the shape functions, their derivatives, both, or none.
[in]	points	A 2D array whose (i, j) element is the ith coordinate of the jth point at which the shape functions and/or their derivatives shall be evaluated.
[in]	localDofIndex.	If set to ALL_DOFS, all the shape functions from the shapeset shall be evaluated; otherwise only the localDofIndex'th function shall be evaluated.
[out]	basisData	Receives evaluation results.

If what contains the flag VALUES, on output basisData.values(i, k, l) shall contain the value of the ith component of the kth evaluated shape function at the lth point.

If what contains the flag DERIVATIVES, on output basisData.derivatives(i, j, k, l) shall contain the derivative in direction j of the ith component of the kth evaluated shape function at the lth point.

Implements Fiber::Shapeset< ValueType >.
