Returns the global (x,y,z) indices of the lower left corner and size of the local region, excluding ghost points.
da - the distributed array
x - the corner index for the first dimension
y - the corner index for the second dimension (only used in 2D and 3D problems)
z - the corner index for the third dimension (only used in 3D problems)
m - the width in the first dimension
n - the width in the second dimension (only used in 2D and 3D problems)
p - the width in the third dimension (only used in 3D problems)
The corner information is independent of the number of degrees of
freedom per node set with the
DMDACreateXX() routine. Thus the x, y, z, and
m, n, p can be thought of as coordinates on a logical grid, where each
grid point has (potentially) several degrees of freedom.
Any of y, z, n, and p can be passed in as NULL if not needed.
