EPSKrylovSchurSetDimensions

Sets the dimensions used for each subsolve step in case of doing spectrum slicing for a computational interval. The meaning of the parameters is the same as in EPSSetDimensions().

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSKrylovSchurSetDimensions(EPS eps,PetscInt nev,PetscInt ncv,PetscInt mpd)

Input Parameters

eps  - the eigenproblem solver context
nev  - number of eigenvalues to compute
ncv  - the maximum dimension of the subspace to be used by the subsolve
