Data structure (C struct) for storing information about a single row or column of a matrix as indexed on an associated grid. These are arguments to
The i,j, and k represent the logical coordinates over the entire grid (for 2 and 1 dimensional problems the k and j entries are ignored).
The c represents the the degrees of freedom at each grid point (the dof argument to
DMDASetDOF()). If dof is 1 then this entry is ignored.
For stencil access to vectors see
Fortran usage is different, see
MatSetValuesStencil() for details.
