PetscDTStroudConicalQuadrature

create Stroud conical quadrature for a simplex [KS05]

Synopsis

#include "petscdt.h" 
PetscErrorCode PetscDTStroudConicalQuadrature(PetscInt dim, PetscInt Nc, PetscInt npoints, PetscReal a, PetscReal b, PetscQuadrature *q)

Not Collective

Input Parameters

• dim - The simplex dimension

• Nc - The number of components

• npoints - The number of points in one dimension

• a - left end of interval (often-1)

• b - right end of interval (often +1)

Output Parameter

• q - A PetscQuadrature object

Note

For dim == 1, this is Gauss-Legendre quadrature
