Detailed Description

template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HGRAD_LINE_C1_FEM< Scalar, ArrayScalar >

Implementation of the default H(grad)-compatible FEM basis of degree 1 on Line cell.

Implements Lagrangian basis of degree 1 on the reference Line cell. The basis has cardinality 2 and spans a COMPLETE linear polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:

  |         |           degree-of-freedom-tag table                    |                           |
  |   DoF   |----------------------------------------------------------|      DoF definition       |
  | ordinal |  subc dim    | subc ordinal | subc DoF ord |subc num DoF |                           |

void Intrepid::Basis_HGRAD_LINE_C1_FEM< Scalar, ArrayScalar >::getValues ( ArrayScalar &  outputValues,
const ArrayScalar &  inputPoints,
const EOperator  operatorType 
) const [virtual]

Evaluation of a FEM basis on a reference Line cell.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference Line cell. For rank and dimensions of I/O array arguments see Section MD array template arguments for basis methods .

outputValues[out] - variable rank array with the basis values
inputPoints[in] - rank-2 array (P,D) with the evaluation points
operatorType[in] - the operator acting on the basis functions

Implements Intrepid::Basis< Scalar, ArrayScalar >.
