DMPlexProjectFunction

This projects the given function into the function space provided.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexProjectFunction(DM dm, PetscInt numComp, void (**funcs)(const PetscReal [], PetscScalar *), InsertMode mode, Vec X)

Input Parameters

	dm	- The DM
	numComp	- The number of components (functions)
	funcs	- The coordinate functions to evaluate
	mode	- The insertion mode for values

Output Parameter

X -vector

Note

This currently just calls the function with the coordinates of each vertex and edge midpoint, and stores the result in a vector. We will eventually fix it.
