Hello, I'm having a lot of fun converting python code from numarray to numpy and I just found out that the alter_code1.py conversion script changes numarray's '.stddev()' to numpy's '.std()', even though the semantics are different ("sample" std.dev. or not; divide by N-1 vs. by N). Should I open yet another ticket about '.std()'? http://projects.scipy.org/scipy/numpy/ticket/502 http://projects.scipy.org/scipy/numpy/ticket/461 http://projects.scipy.org/scipy/numpy/ticket/388 This will be easy to solve once .std() has a parameter to choose the divisor, but what is everybody using in the mean time? Thanks, Xavier Saint-Mleux
