If mlab is supposed to be compatible with matlab, then isn't this a problem?

 From matlab, version 7.2.0.283 (R2006a)

 >> prctile([1 1 2 2 1 2 4 3 2 2 2 3 4 5 6 7 8 9 7 6 4 5 5],[0 25 50 75 
100])

ans =

    1.0000    2.0000    4.0000    5.7500    9.0000


Of course, the 75th percentile is different here too (5.75 instead of 
scipy's 5.5).  I don't know how to explain that discrepancy.
