+function varargout = mex_generate_coarsegrid(varargin)
+%Build coarse grid data structure from partition of existing grid (MEX)
+%
+% SYNOPSIS:
+%   CG = mex_generate_coarsegrid(G, p)
+%
+% PARAMETERS:
+%   G - Grid data structure as described in 'grid_structure'.
+%
+%   p - Partition vector as defined by, e.g., functions 'partitionUI' or
+%       'partitionNonUniform'.
+%
+% RETURNS:
+%   CG - Coarse grid data structure as described in 'generateCoarseGrid'.
+%        There is, however, a number of subtle differences in the details
+%        of this structure as compared to the pure M implementation.
+%        Specifically, the coarse faces are numbered differently, and the
+%        MEX implementation does not distinguish cardinal directions whence
+%        the 'subFaces' function does not produce meaningful results on
+%        outer faces.
+%

+%   generateCoarseGrid.
