[petsc-users] Storage space for symmetric (SBAIJ) matrix

[Daniel Langr]

Jed,

thanks much for your comprehensive answer, it will certainly help. I 
will look at the example codes. As for matrix assembly process, I would 
prefer constructing a matrix from arrays (to avoid dynamic assembly and 
additional memory costs) but there is nothing like 
MatCreateMPISBAIJWithArrays() or better 
MatCreateMPISBAIJWithSplitArrays() for symmetric matrices as for 
unsymmetric ones in PETSc.

Regards,
Daniel
