Hi Timothy, thank you for your feedback. And for the suggestion! I just got started with github and am building some tutorials on this in Python (you can check it at github.com/mycarta), but it did not occurr to me to upload the Matlab code as well. Great idea, I'll get to it as soon as I'm done with the Python tutorials.

Hi Jakob, thanks for the positive feedback and for pointing that out. I am working on some additional colormaps so when I add those I will also fix the interp1 commands.

Great colormap

Zack L-B: thanks, I must have loaded an older file accidentally. I just loaded the intended update (2014).

John: I did not know you could do this:
>> X=(5:-1:-1)
X = 5 4 3 2 1 0 -1
>> X1=max(X,0)
X1 = 5 4 3 2 1 0 0
Wonderful, thanks for the great suggestion, I'll add that.

Fantastic colormap! Have you though of placing your code and progress on github as well? That way we can fork, patch, or just update our copies very easily. Thank you again.

Works fine! An easy to use implementatoin of the color maps explained in the Mycarta blog. One minor issue: running the code I get a compatibility warning ("Warning: INTERP1(...,'CUBIC') will change in a future release. Use INTERP1(...,'PCHIP') instead."). Maybe this should be fixed in the next version.
