- %COLORMENU Add a color map menu to the current figure.
- % Each of the menu choices operates on the colormap:
- % HOT, PINK, COOL, BONE, JET, COPPER, FLAG and PRISM are names of
- % functions which generate color maps.
- % RAND is a random color map.
- % BRIGHTEN increases the brightness.
- % DARKEN decreases the brightness.
- % FLIPUD inverts the order of the colormap entries.
- % FLIPLR interchanges the red and blue components.
- % PERMUTE cyclic permuations: red -> blue, blue -> green, green -> red.
- % SPIN spins the colormap, which is a rapid sequence of FLIPUD's.
- % REMEMBER pushes a copy of the current color map onto a stack.
- % RESTORE pops a map from the stack (initially, the stack contains the
- % map in use when COLORMENU was invoked.)
