Detailed Description

template<typename DeviceType, typename ValueType>
class Intrepid2::ProjectionStruct< DeviceType, ValueType >

An helper class to compute the evaluation points and weights needed for performing projections.

In order to perform projections, the basis functions and the target function need to be evaluated at several sets of evaluation points (cubature points) defined on subcell entities (edges, faces, volumes). Depending on the projection, the evaluation of derivatives of the basis functions and of the target function may be needed as well. This class provides a struct to store the evaluation points/weights on the reference cell.

Use: create the proper ProjectionStruct rule by calling one of the functions: createL2ProjectionStruct, createHGradProjectionStruct, createHCurlProjectionStruct, createHDivProjectionStruct, createHVolProjectionStruct, depending on the type of projection wanted.

The created class is then used with the Projection Tools. See ProjectionTools class for more info.
