TSMonitorSPEig

Monitors the eigenvalues of the linearized right-hand-side operator on a scatter plot at each time step

Synopsis

#include "petscts.h"  
PetscErrorCode TSMonitorSPEig(TS ts, PetscInt step, PetscReal ptime, Vec v, void *monctx)

Collective

Input Parameters

• ts - the TS context

• step - the current time-step number (a negative value indicates an interpolated solution and is ignored)

• ptime - the current time

• v - the current solution

• monctx - the TSMonitorSPEigCtx context, created with TSMonitorSPEigCtxCreate()

Options Database Key

• -ts_monitor_sp_eig - plot eigenvalues of linearized right-hand side

Notes

This is not called directly by users; pass this function to TSMonitorSet() along with the context created by TSMonitorSPEigCtxCreate() and TSMonitorSPEigCtxDestroy().

Currently only works when the Jacobian is provided explicitly and the ODE has no mass matrix.
