I would like to find percentiles, with interpolation where needed, but the matplotlib prctile seems to be different to matlab in this respect: In [1]: x = array([ 3.0, 5.0, 7.0, 8.0, 9.0, 11.0 ]) In [2]: median(x) Out[2]: 7.5 In [3]: prctile(x,50) Out[3]: 8.0 is there a function available which does include interpolation, or should I just write my own? (I'd also like 10th and 90th percentiles for example). Thanks, Dave
