  • scipy array tip sheet

    Arrays are the central datatype introduced in the SciPy package. (The same array objects are accessible within the NumPy package, which is a subset of SciPy. For consistency, we will simplify refer to to SciPy, although some of the online documentation makes reference to NumPy. And technically, array objects are of type ndarray, which stands for "n-dimensional array".) The array interface is acces

  • scipy.arrayで部分行列

    pythonの科学計算用ライブラリscipyのarrayの使い方が忘れやすいのでメモ. scipy.arrayを使って行列から部分行列にアクセスする時には, array[ 行開始:行終了, 列開始:列終了 ] または array[ 行開始:行終了 ][ 列開始:列終了 ] ※ だたし,例えばarray[:][0:1]としても列ベクトルは取れない(array[:,0:1]なら大丈夫)ので,前者にそろえるのが良いと思います. とします.省略可能なのは, 開始の0 終了が行か列の最後 ipythonでの実行例: In [1]: import scipy In [2]: a=scipy.array([[11,12,13],[21,22,23],[31,32,33]]) In [3]: a Out[3]: array([[11, 12, 13], [21, 22, 23], [31, 32, 33]

  • Probability distributions in SciPy | Python

    Here are some notes on how to work with probability distributions using the SciPy numerical library for Python. Functions related to probability distributions are located in scipy.stats. The general pattern is scipy.stats.<distribution family>.<function> There are 81 supported continuous distribution families and 12 discrete distribution families. Some distributions have obvious names: gamma, cauc
