Hello, I create a MPIAIJ matrix. How can I know the # of nonzeros stored locally? Furthermore, in case it is needed, how can I get access to the Compress Sparse Row(CSR) data structure of the local matrix, i.e., the row pointer array, column index array, value array?
Thank you! -- Junchao Zhang -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-users/attachments/20111229/5090bd59/attachment.htm>
