<title>Description</title>
<para>colormap(M) sets the current figure's colormap to M.</para>
<para>M = colormap() retrieves the current colormap. The values are in the
range from 0 to 1. M is a m x 3 matrix. m is the number of colors. Color
number i is given as a 3-uple M(i,1), M(i,2), M(i,3) corresponding
respectively to red, green and blue intensity. For example, [0 0 0] is
black, [1 1 1] is white, [1 0 0] is pure red, [.5 .5 .5] is gray, and
[127/255 1 212/255] is aquamarine.</para>
