#include "slepcst.h" PetscErrorCode STFilterSetInterval(ST st,PetscReal inta,PetscReal intb)Logically Collective on st
st | - the spectral transformation context | |
inta | - left end of the interval | |
intb | - right end of the interval |
-st_filter_interval <a,b> | - set [a,b] as the interval of interest |
Common usage is to set the interval in EPS with EPSSetInterval().
The interval must be contained within the numerical range of the matrix, see STFilterSetRange().
