I want to get the inverse matrix of 10 x 10 MATMPIDENSE matrix. I know I cannot use MatLUFactor() for MATMPIDENSE. Is there any other method? Could you let me know the fastest way to get the inverse? Also, I don't want to rebuild or configure something for the inverse because I use petsc in my school server and I don't have permission to configure.
