Your faithfully:
Can you tell me whether I need to caculate the exact diag and off-diag
arrays related to the nonzeros numbers when I use subroutine
MatMPIBAIJSetPreallocationCSR to allocate memory?
I have read this website
"http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MatMPIAIJSetPreallocationCSR.html";,
but I don't understand it clealy. So can you tell me where can I find the
example of MatMPIBAIJSetPreallocationCSR?
Thanks!
your sincerely
