COLD Black-Blue-Cyan-White Color Map

COLD(M) returns an M-by-3 matrix containing a "cold" colormap
COLD, by itself, is the same length as the current figure's colormap. If no figure exists, MATLAB creates one.

Example:
imagesc(peaks(500))
colormap(cold); colorbar

Example:
load topo
imagesc(0:360,-90:90,topo), axis xy
colormap(cold); colorbar

Hi Joseph,
Great code. I also found that this code works;

cmap = colormap(1-hot);
cmap(1,:) = [1 1 1]; %Pure white

I like your submission. Simple, well written code. Your example inspired me to make a similar one for my Perceptually improved colormaps submission.

You might add a see also for cool, an existing colormap with a slightly different shape in terms of colors.

Regardless, this adds another colormap option. As always, the help is what I'd expect.

Added "cool" to the "See also" section, as suggested.
