[petsc-users] Questions abt ex22f

[TAY wee-beng]

Hi,

I am using petsc-dev 2012-04-20.

Btw, I'm referring to :

http://www.mcs.anl.gov/petsc/petsc-dev/src/ksp/ksp/examples/tutorials/ex22f.F.html

Part of the code is :

call KSPSetFromOptions(ksp,ierr)
       call KSPSetUp(ksp,ierr)
       call KSPSolve(ksp,PETSC_NULL_OBJECT,PETSC_NULL_OBJECT,ierr)
       call KSPDestroy(ksp,ierr)
       call DMDestroy(da,ierr)
       call PetscFinalize(ierr)



Unlike other codes like ex29c or ex45c, there isn't a "call 
KSPGetSolution(ksp,x,ierr)"

Also I want to add "call VecView(x,ierr)" to print out the results, 
which is usally added after the above.

Thank you

Yours sincerely,

TAY wee-beng
