[petsc-users] MatPartitioningSetVertexWeights

[Lukasz Kaczmarczyk]

Hello,

In petsc file pmetsi.c (petsc-3.3), the flag wgtflag=0 (line 60), what indicate that there are no weights (vwgt and adjwgt are both NULL). This makes use MatPartitioningSetVertexWeights without any effect. 

Kind regards,
Lukasz
