MatCreateMPIAIJWithSplitArrays() cannot be used to set some off-
processor entries; it sets only local rows. Also you cannot later set
off-processor values into this matrix with MatSetValues().
This is rather a special routine designed for people who already
have the entire sparse matrix setup in parallel CSR format. For
general usage where you set values with MatSetValues() you should use
MatCreateMPIAIJ()
