Hi,
Now I came up with this new problem, I could not find the way to let petsc mat store double precision values. I used double precision value in MatSetValue() but the MatView showed the stored data to be single precision. I've also tried to recompile petsc as:
I think you are misinterpreting MatView(). Matt
./config/configure.py --with-precision=double
which didnot work for me.
Thanks very much.
