[Numpy-discussion] Scientific Python at SIAM CSE 2011 conference

2011-04-06 Thread Fernando Perez
Hi all, sorry for the massive cross-post, but since all these projects were highlighted with talks at this event, I figured there would be interest... Hans-Petter Langtangen, Randy LeVeque and I organized a set of Python-focused sessions at the recent SIAM Computational Science and Engineering

[Numpy-discussion] strange behavior of np.minimum and np.maximum

2011-04-06 Thread Emmanuelle Gouillart
Hello, a, b, c = np.array([10]), np.array([2]), np.array([7]) min_val = np.minimum(a, b, c) min_val array([2]) max_val = np.maximum(a, b, c) max_val array([10]) min_val array([10]) (I'm using numpy 1.4, and I observed the same behavior with numpy 2.0.0.dev8600 on another machine).

Hi Zach and Derek, thank you very much for your quick and clear answers. Of course the third parameter is the out array, I was just being very stupid! (I had read the documentation though, but somehow it didn't make it to my brain :-) Sorry... Read the documentation for numpy.minimum and

[Numpy-discussion] Rounding the decimal part of a real number

2011-04-06 Thread dileep kunjaai
Dear sir, Is there any function for rounding the real number, for n (say) decimal places: Example: Let X= 6.9867349234888211237767867863478728314... but i need only 4 decimal position. That is the answer should be.. answer=6.9867 -- DILEEPKUMAR. R J R F, IIT DELHI
