MATLAB: How to reverse colormap in contourfm

mappingMapping ToolboxMATLAB

I'd like to use the reverse of jet colormap in contourfm. contourfm seems to only accept standard string values for predefined colormaps.

?? MATLAB's contourfm does not have a colormap argument at all, let alone a string.

If you want to reverse the colormap, just do it:

colormap(flipud(jet))

Grab the colormap and flip it upside down:

f = figure;
surf(peaks(50))
colormap(f, flipud(colormap(f)))
colorbar

colormap( flipud(gray(256)) )

gray(256) would normally be brighter for higher values, so you reverse the order of the colors to get darker for higher values.
