RGEllipseSetParameters
Sets the parameters defining the ellipse region.
Synopsis
#include "slepcrg.h"
PetscErrorCode RGEllipseSetParameters(RG rg,PetscScalar center,PetscReal radius,PetscReal vscale)
Logically Collective
Input Parameters
| rg | - the region context
|
| center | - center of the ellipse
|
| radius | - radius of the ellipse
|
| vscale | - vertical scale of the ellipse
|
Options Database Keys
| -rg_ellipse_center | - Sets the center
|
| -rg_ellipse_radius | - Sets the radius
|
| -rg_ellipse_vscale | - Sets the vertical scale
|
Notes
In the case of complex scalars, a complex center can be provided in the
command line with [+/-][realnumber][+/-]realnumberi with no spaces, e.g.
-rg_ellipse_center 1.0+2.0i
When PETSc is built with real scalars, the center is restricted to a real value.
