CC_GRID_DISPLAY displays a single Clenshaw Curtis 2D grid of orders M by N:

• cc_grid_2x16.png, a PNG image of a 2 by 16 Clenshaw Curtis grid.
• cc_grid_5x9.png, a PNG image of a 5 by 9 Clenshaw Curtis grid.

CC_GRIDS_MINMAX_DISPLAY displays all Clenshaw Curtis grids of orders M by N such that M+N is between Q_MIN and Q_MAX:

• cc_grids_minmax_2to2.png, a PNG image of Clenshaw Curtis grids with Q_MIN = Q_MAX = 2.
• cc_grids_minmax_3to3.png, a PNG image of Clenshaw Curtis grids with Q_MIN = Q_MAX = 3.
• cc_grids_minmax_4to4.png, a PNG image of Clenshaw Curtis grids with Q_MIN = Q_MAX = 4.

CC_LEVELS_MINMAX_DISPLAY displays all Clenshaw Curtis grids of levels M by N such that M+N is between LEVEL_MIN and LEVEL_MAX. Note that the order, or number of points, in the one dimensional rules, is related to the one dimensional levels by ORDER=2**LEVEL+1 (except that the LEVEL=0 corresponds to ORDER=1):

• cc_levels_minmax_2to2.png, a PNG image of Clenshaw Curtis grids with LEVEL_MIN = LEVEL_MAX = 2.
• cc_levels_minmax_3to3.png, a PNG image of Clenshaw Curtis grids with LEVEL_MIN = LEVEL_MAX = 3.
• cc_levels_minmax_4to4.png, a PNG image of Clenshaw Curtis grids with LEVEL_MIN = LEVEL_MAX = 4.
• cc_levels_minmax_5to5.png, a PNG image of Clenshaw Curtis grids with LEVEL_MIN = LEVEL_MAX = 5.
• cc_levels_minmax_6to6.png, a PNG image of Clenshaw Curtis grids with LEVEL_MIN = LEVEL_MAX = 6.
