Hi all
I am very new to petsc and to c programming. I need to build a huge sparse matrix with a block structure.
The problem is that my matrx may be huge (200000*200000) so i Need a way to define it through the kronecker product or memorizing just the overdiagonal, diagonal and subdiagonal block.
Is it possible in petsc? any suggestions?
thanks a million in advance
