PetscRealSortSemiOrdered#

Sorts an array of PetscReal in place in increasing order.

Synopsis#

Not Collective

Input Parameters#

  • n - number of values

  • arr - array of PetscReal

Output Parameter#

  • 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.
