PURPOSE ^

% MAKECOLORMAP makes smoothly varying colormaps

SYNOPSIS ^

function cMap = makecolormap(varargin)

DESCRIPTION ^

% MAKECOLORMAP makes smoothly varying colormaps
 a = makeColorMap(beginColor, middleColor, endColor, numSteps);
 a = makeColorMap(beginColor, endColor, numSteps);
 a = makeColorMap(beginColor, middleColor, endColor);
 a = makeColorMap(beginColor, endColor);

 all colors are specified as RGB triples
 numSteps is a scalar saying howmany points are in the colormap

 Examples:

 peaks;
 a = makeColorMap([1 0 0],[1 1 1],[0 0 1],40);
 colormap(a)
 colorbar

 peaks;
 a = makeColorMap([1 0 0],[0 0 1],40);
 colormap(a)
 colorbar

 peaks;
 a = makeColorMap([1 0 0],[1 1 1],[0 0 1]);
 colormap(a)
 colorbar

 peaks;
 a = makeColorMap([1 0 0],[0 0 1]);
 colormap(a)
 colorbar
