This function is useful if you don't want to use the linear scaled colormap that are the default in Matlab.
% cbar_labels - Vector (n x 1) of monotonically increasing ranges of data
% user_cmap - Matrix ((n-1) x 3) of colormap you want to see
% minMaxValues - Vector (2 x 1) of minimum and maximum value of data
% that is plotted
data = rand(10,10);
minVal = min(min(data));
maxVal = max(max(data));
cbar_labels = [0 0.12 0.2 0.3 0.5 0.6 0.75 0.8 1]; % user defined ranges
user_cmap = jet(8); % user defined colormap
Bug and comments are welcome.

Great Function. Love it.
The only issue is, when making maps with contourf() with EdgeColor on and changing subsequently the colors with CUSTOMCMAP(), the isolines are wrong (still the old ones). However, that's not a real issue / not the job of CUSTOMCMAP()
It does not seems to compatible to subplot.
How should I adjust it so that I can show gradients between labels?
Minor bug fixed.
