Dear PETSc Team,
I am using the latest petsc version 3.20.5. I would like to create a matrix using MatCreateSeqAIJ To insert values, I use MatSetValues. It seems that the Fortran interface/stubs are missing for MatsetValues, as the linker does not find any subroutine with that name. MatSetValueLocal seems to be fine. Typically I am using a blocked matrix format (BAIJ), which works fine in fortran. Soon we want to try PETSC on GPUs, using the format MATAIJCUSPARSE, since there seems not to be a blocked format available in PETSC for GPUs so far. Therefore I first want to try the pointwise format MatCreateSeqAIJ format on a CPU, before using the GPU format. I think that CUDA also supports a block format now ?! Maybe that would be also useful to have one day. Greetings, Frank Bramkamp
