Re: petsc: symmetric matrix



Satish,

This questions seems to be asked on the average of once per week on
this list. Perhaps a section on symmetric matrics could be added
to the manual?

Hi, all
   when I create a matrix with MatCreateSeqAIJ() and the matrix is
symmetry,how can I complete it while only the half data is inserted
? does the memory needed be half of the same scale matrix but not
symmetry ? if not,how should i set it ?
thanks

You'll have to use MatCreateSeqSBAIJ() for this purpose.
