RGCheckInside
Determines if a set of given points are inside the region or not.
Synopsis
#include "slepcrg.h"
PetscErrorCode RGCheckInside(RG rg,PetscInt n,PetscScalar *ar,PetscScalar *ai,PetscInt *inside)
Not Collective
Input Parameters
| rg | - the region context
|
| n | - number of points to check
|
| ar | - array of real parts
|
| ai | - array of imaginary parts
|
Output Parameter
| inside | - array of results (1=inside, 0=on the contour, -1=outside)
|
Note
The point a is expressed as a couple of PetscScalar variables ar,ai.
If built with complex scalars, the point is supposed to be stored in ar,
otherwise ar,ai contain the real and imaginary parts, respectively.
If a scaling factor was set, the points are scaled before checking.
