RGIsAxisymmetric#

Determines if the region is symmetric with respect to the real or imaginary axis.

Synopsis#

#include "slepcrg.h" 
PetscErrorCode RGIsAxisymmetric(RG rg,PetscBool vertical,PetscBool *symm)

Not Collective

Input Parameters#

  • rg - the region context

  • vertical - true if symmetry must be checked against the vertical axis

Output Parameter#

  • symm - true if the region is axisymmetric

Note#

If the vertical argument is true, symmetry is checked with respect to the vertical axis, otherwise with respect to the horizontal axis.
