da | - the distributed array | |
vec | - the vector | |
dir | - Cartesian direction, either DM_X, DM_Y, or DM_Z | |
gp | - global grid point number in this direction |
newvec | - the new vector that can hold the values (size zero on all processes except process 0) | |
scatter | - the VecScatter that will map from the original vector to the slice |
