PetscDualSpaceLagrangeSetNodeType

Set a description of how nodes are laid out for Lagrange polynomials in this dual space

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceLagrangeSetNodeType(PetscDualSpace sp, PetscDTNodeType nodeType, PetscBool boundary, PetscReal exponent)
Logically collective

Input Parameters

sp - The PetscDualSpace
nodeType - The type of nodes
boundary - Whether the node type is one that includes endpoints (if nodeType is PETSCDTNODES_GAUSSJACOBI, nodes that include the boundary are Gauss-Lobatto-Jacobi nodes)
exponent - If nodeType is PETSCDTNODES_GAUSJACOBI, indicates the exponent used for both ends of the 1D Jacobi weight function '0' is Gauss-Legendre, '-0.5' is Gauss-Chebyshev of the first type, '0.5' is Gauss-Chebyshev of the second type
