function c = copper(m)
%COPPER	Linear copper-tone color map.
%	COPPER(M) returns an M-by-3 matrix containing a "copper" colormap.
%	COPPER, by itself, is the same length as the current colormap.
%
%	For example, to reset the colormap of the current figure:
%
%	          colormap(copper)
%
%	See also HSV, GRAY, HOT, COOL, BONE, PINK, FLAG, 
%	COLORMAP, RGBPLOT.
