PetscDualSpaceLagrangeGetNodeType#

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

Synopsis#

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceLagrangeGetNodeType(PetscDualSpace sp, PetscDTNodeType *nodeType, PetscBool *boundary, PetscReal *exponent)

Not Collective

Input Parameter#

Output Parameters#

  • 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
