Copper colormap array
c = copper
c = copper(m)
c = copper returns the copper colormap
as a three-column array with the same number of rows as the colormap
for the current figure. If no figure exists, then the number of rows
is equal to the default length of 64. Each row in the array contains
the red, green, and blue intensities for a specific color. The intensities
are in the range [0,1], and the color scheme looks like this image.
Plot a surface and assign the copper colormap.
Get the copper colormap array and reverse the order. Then apply the modified colormap to the surface.
c = copper; c = flipud(c); colormap(c);
Get a downsampled version of the copper colormap containing only ten colors. Then display the contours of the peaks function by applying the colormap and interpolated shading.
c = copper(10); surf(peaks); colormap(c); shading interp;
