PetscRealSortSemiOrdered#
Sorts an array of PetscReal in place in increasing order.
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscRealSortSemiOrdered(PetscInt n, PetscReal arr[])
Not Collective
Input Parameters#
n - number of values
arr - array of
PetscReal
Output Parameters#
arr - sorted array of integers
Notes#
If the array is less than 64 entries long PetscSortReal() is automatically used.
This function serves as an alternative to PetscSortReal(). While this function works for any array of PetscReal it is
significantly faster if the array is not totally random. There are exceptions to this and so it is highly
recommended that the user benchmark their code to see which routine is fastest.
