[petsc-users] Jacobian of TS problem

[yuxuan]

Hi all,


I am running the example:
http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-3.1/src/ts/examples/tutorials/ex7.c


I found that there is no user-provided jacobian data structure function for Finite Difference Jacobian Approximation. And also how can I have look at the values of the Jacobian Matrix. The Matview can show the value, however how I can call it within the solving processes. 


Thanks


Xuan
