NOTE: this function is now available from the IoSR Matlab Toolbox as iosr.figures.cmrMap.
-------------------------
Create a monochrome-compatible colour map

cmap = CMRmap
cmap = CMRmap(M)

cmap = CMRmap returns a colour map CMAP (varying black - purple - red - yellow - white) that is monochrome-compatible, i.e. it produces a monotonic greyscale colour map. CMAP is size Mx3, where M is the length of the current figure's colormap. If no figure exists, MATLAB creates one.

cmap = CMRmap(M) sets the colormap length to M.

The map is a slight modification to that suggested in [1].

EXAMPLE

figure;
imagesc(peaks(1000));
colormap(CMRmap(256));
axis image;
colorbar
