Re: [petsc-users] Nonconforming object sizes in axpy

Thanks a lot, now it is working.   I see the error now. You should pass SUBSET_NONZERO_PATTERN as MatStructure argument to MatAXPY DIFFERENT_NONZERO_PATTERN now triggers preallocation, and MATELEMENTAL does not support MatGetRow.   On Feb 27, 2019, at 3:59 PM, Marius Buerkle

Hello, I try to use the Hypre boomeramg preconditioner but I keep getting type conversion errors like this one for PetscOptionsSetValue(...): Fehler: »const char*« kann nicht nach »PetscOptions« {aka »_n_PetscOptions*«} umgewandelt werden

Re: [petsc-users] Problem in loading Matrix Market format

Eda, An update to ex72 is merged to PETSc master branch just now. It now can read matrices either symmetric or non-symmetric in Matrix Market format, and output a petsc binary matrix in MATSBAIJ format (for symmetric) or MATAIJ format (for non-symmetric). See help in source code for usage.

Don't know why it should cause problems. I'd rather try before asking. > El 28 feb 2019, a las 9:21, Eda Oktay escribió: > > Dear Professor Roman, > > Thank you for your answer. I used PetscBinaryWrite.m file and converted > matrices into binary format but I have a question: > > When I look

Re: [petsc-users] Problem in loading Matrix Market format

Dear Professor Roman, Thank you for your answer. I used PetscBinaryWrite.m file and converted matrices into binary format but I have a question: When I look at Properties of the binary files Petsc have, their type is stated as "Program (application/octet-stream)", however when I checked the
