#include "petscdt.h" PetscErrorCode PetscDTJacobiEvalJet(PetscReal alpha, PetscReal beta, PetscInt npoints, const PetscReal points[], PetscInt degree, PetscInt k, PetscReal p[])
alpha | - the left exponent of the weight | |
beta | - the right exponetn of the weight | |
npoints | - the number of points to evaluate the polynomials at | |
points | - [npoints] array of point coordinates | |
degree | - the maximm degree polynomial space to evaluate, (degree + 1) will be evaluated total. | |
k | - the maximum derivative to evaluate in the jet, (k + 1) will be evaluated total. |
p | - an array containing the evaluations of the Jacobi polynomials's jets on the points. the size is (degree + 1) x (k + 1) x npoints, which also describes the order of the dimensions of this three-dimensional array: the first (slowest varying) dimension is polynomial degree; the second dimension is derivative order; the third (fastest varying) dimension is the index of the evaluation point. |
