[petsc-users] MatGetRowMinAbs - argument is not optional

[Dominik Szczerba]

According to:

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MatGetRowMinAbs.html

the 3rd arg should be optional, but if it is omitted, a compile error
occurs (too few arguments...). The same case with MatGetRowMaxAbs.
