%DAWN Black-purple-blue-green-yellow-white colormap
%
% Examples:
% map = dawn;
% map = dawn(len);
% B = dawn(A);
% B = dawn(A, lims);
%
% A black to white colormap with several distinct pastel shades reminiscent
% of colors at dawn. This colormap has been designed to achieve perceptual
% uniformity.
%
% The function can additionally be used to convert a real-valued array into
% a truecolor array using the colormap.
%
% IN:
% len - Scalar length of the output colormap. If len == Inf the concise
% table is returned. Default: len = size(get(gcf, 'Colormap'), 1);
% A - Non-scalar numeric array of real values to be converted into
% truecolor.
% lims - 1x2 array of saturation limits to be used on A. Default:
% [min(A(:)) max(A(:))].
%
% OUT:
% map - (len)x3 colormap table of RGB values in the range [0,1].
% B - size(A)x3 truecolor array.
