28 Apr 2013 contourfill Fills area between TWO contour levels. Author: Lukas Chvatal

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

23 Apr 2013 Three dimensional implementation of the Canny edge detection Can be used to detected surfaces from a 3D volume. Author: boyexex

Same error as CH for me.
14 Mar 2013 Mann-Whitney-Wilcoxon test Mann-Whitney-Wilcoxon non parametric test for two unpaired groups. Author: Giuseppe Cardillo

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:
STATS.auc = U / (L(1)*L(2));

13 Mar 2013 Mann-Whitney-Wilcoxon test Mann-Whitney-Wilcoxon non parametric test for two unpaired groups. Author: Giuseppe Cardillo

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:
[p h stats] = ranksum(1:100,11:110)
p: 0.0203

stats = mwwtest(1:100,11:110)
stats.p: 0.0102

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.

Very nice.

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

Thank you!
