Creates a context for use with TS to monitor the eigenvalues of the linearized operator


#include "petscts.h"  
PetscErrorCode  TSMonitorSPEigCtxCreate(MPI_Comm comm,const char host[],const char label[],int x,int y,int m,int n,PetscInt howoften,TSMonitorSPEigCtx *ctx)
Collective on TS

Input Parameters

host - the X display to open, or null for the local machine
label - the title to put in the title bar
x, y - the screen coordinates of the upper left coordinate of the window
m, n - the screen width and height in pixels
howoften - if positive then determines the frequency of the plotting, if -1 then only at the final time

Output Parameter

ctx -the context

Options Database Key

-ts_monitor_sp_eig -plot egienvalues of linearized right hand side


Use TSMonitorSPEigCtxDestroy() to destroy.

Currently only works if the Jacobian is provided explicitly.

Currently only works for ODEs u_t - F(t,u) = 0; that is with no mass matrix.
