Detailed Description

Restricted Element-Wise Projection operator.

This class template implements the "restricted element-wise projection" operator which projects an (analytic) function into a Finite-Element space by performing weighted element-wise L2-projections.

inlinestatic

Projects an analytic function into a finite element space.

Parameters

[out]	vector	A transient reference to the coefficient vector that is to be assembled. The vector is automatically allocated by this function, so it does not need to be allocated beforehand.
[in]	function	A transient reference to an object implementing the AnalyticFunction interface capable of computing function values.
[in]	space	A transient reference to the space to which to project into.
[in]	cubature_factory	A cubature factory to be used for integration.
[in]	weight_type	The weighting type to be used.
