EPSSolve

Solves the eigensystem.

Synopsis

#include "slepceps.h" 
int EPSSolve(EPS eps,int *its) 
Collective on EPS

Input Parameter

eps -eigensolver context obtained from EPSCreate()

Output Parameter

its -number of iterations performed by the solver

Options Database

-eps_view - print information about the solver used
-eps_view_binary - save the matrices to the default binary file
-eps_plot_eigs - plot computed eigenvalues

Notes

On return, the parameter "its" contains either the iteration number at which convergence was successfully reached, or failure was detected. Call EPSGetConvergedReason() to determine if the solver converged or failed and why.
