RGIntervalSetEndpoints

Sets the parameters defining the interval region.

Synopsis

#include "slepcrg.h" 
PetscErrorCode RGIntervalSetEndpoints(RG rg,PetscReal a,PetscReal b,PetscReal c,PetscReal d)
Logically Collective on RG

Input Parameters

rg - the region context
a,b - endpoints of the interval in the real axis
c,d - endpoints of the interval in the imaginary axis

Options Database Keys

-rg_interval_endpoints - the four endpoints

Note

The region is defined as [a,b]x[c,d]. Particular cases are an interval on the real axis (c=d=0), similar for the imaginary axis (a=b=0), the whole complex plane (a=-inf,b=inf,c=-inf,d=inf), and so on.
