Re: [petsc-users] DMDASetBlockFillsSparse format

I looked at the code and in the end the values get propagated into calls to MatSetValuesLocal() which does not require sorted values. Thus my conclusion is that you do not have to sorted column indices in these calls Barry Yes we do a nonexistent job of indicating when indices

Dear All, Does anyone know if the format of sparse matrices in DMDASetBlockFillsSparse require column indicies for chosen row to be in increasing order? Thank you, Oleksandr.

Re: [petsc-users] DMDASetBlockFillsSparse format

I'm pretty confident all the tests are sorted. It wouldn't be any great hardship for us to allow unsorted input. If you submit an unsorted test, we can make sure it works (it might already, but we should probably add a call to in-place sort). Oleksandr Koshkarov via petsc-users writes: > Dear
