This is annoying. You need to pass in a compiler flag to turn off the error
conditioner for casting a function

Hi All,
I would appreciate if you could give some advice for setting the ‘FormFunction’
for the MatFDColoringSetFunction function call.
I follow what is shown in the example:
https://petsc.org/release/src/snes/tutorials/ex14.c.html
I setup similar code structure like:
PetscErrorCode
You can put them in different files or in the same file. If you put them in
the same file you need to know which object comes first the matrix or the
vector, this tells you if you should call MatLoad first or VecLoad.

Hi All,
Back to PETSc-3.8 version, the example ex10.c supports reading matrix
and vector from separated files. Is this feature deprecated in the new
PETSc version? I have some matrix and rhs to test but could not use ex10
example under new PETSc version.
Thanks,
Danyang
