comm | - MPI communicator Many br | |
bs | - the block size, only a block size of 1 is supported Many br | |
m | - number of local rows (Cannot be PETSC_DECIDE) Many br | |
n | - This value should be the same as the local size used in creating the Many brx vector for the matrix-vector product y = Ax. (or PETSC_DECIDE to have Many brcalculated if N is given) For square matrices n is almost always m. Many br | |
M | - number of global rows (or PETSC_DETERMINE to have calculated if m is given) Many br | |
N | - number of global columns (or PETSC_DETERMINE to have calculated if n is given) Many br | |
i | - row indices Many br | |
j | - column indices Many br | |
a | - matrix values Many br |
Many br
The i and j indices are 0 based, and i indices are indices corresponding to the local j array. Many br
