Cool function thanks. It'd be great to add an option for controlling the colors when using multiple levels.

Thank you for your quick response.
Your roc function is indeed very good.
For those who would just want a quick measure of effect size, it's easy to perform the empirical AUC from Giuseppe Cardillo's function by adding:

Thank you very much for this useful function.
Is it normal that the p-values it makes are different from those obtained with matlab's ranksum function:
stats = mwwtest(1:100,11:110)
If so, which one shall we report?
As an addup, I think it would be great to add an output of the effect size using the area under the curve, as well as the confidence interval.

Could you add options to include other types of randomness (gaussian etc)?

Thanks. It would be nice however to allow multiple line plotting such as: ccplot(1:10,rand(200,10),c,map)

Thanks a lot, very useful.
I would remove the absolute computation: ( auc = 0.5 + abs(0.5-auc);) as it is indicative of the effect direction which is necessary for most statistical analyses.

I encountered the following problem under ubuntu.
Warning: You are using gcc version "4.4.3-4ubuntu5)". The earliest gcc version supported
paretofront.c: In function ‘paretofront’:
mex: compile of ' "paretofront.c"' failed.
The way to solve it is to delete the comment at line 83 in the paretofront.c file.
