Sebastian, John (and Petros, long overdue) thanks for the positive rating and feedback.

Joshua, thanks for the rating and comments, and also for spotting the error in the code. I just moved back to Canada after a year in Norway and my computer (with Matlab) is on a slow boat, I will re-submit with the corrected code asap.

Great work, thanks.
BTW I think help menu is exaustive and clearly written.

Very nice idea, never thought about these color perception issues.

There is a small bug in pmkmp.m with my version of MATLAB (8.1.0.604 (R2013a)). When using the edge colormap and n values around 100 (e.g. 128 or 64) I get

>> colormap(pmkmp(128,'edge'))
Error using colormap (line 99)
Colormap must have values in [0,1].

I think this is due to interp1 returning negative values under these circumstances.

Nice,

I just had a long discussion with a colleague a few days ago on "big" anomalies in his plot, which were mainly due to the perception of the chosen colormap (jet).

I really like the "Edge" and "LinearL" colormaps and will must likely start to use them in the future.
