COOL(len)

Optional. An integer, the colormap length. Defaults to the length of the current colormap. |
A table of RGB triples suitable for the SETCOLORMAP function.
clen = length(getcolormap());
density(ravel(rep(0..(clen-1), 32), clen)');
cool;
creates a table of 32 x N (where N == colormap length) RBG values and displays the resulting colors. The resulting image is a vertical plot of colors ranging from aqua (lowest) to violet (highest).
cool by itself sets the colormap and shading.
a = cool or setcolormap(cool) returns the RGB values. In this case, use SETSHADING to make the new colormap take effect on an existing density or 2D plot.
