Python科學計算工具包：NumPy

jopen 11年前發布 | 38K 次閱讀 Python Python開發

NumPy is the fundamental package for scientific computing with Python. It contains among other things:
1）a powerful N-dimensional array object
2）sophisticated (broadcasting) functions
3）tools for integrating C/C++ and Fortran code
4） useful linear algebra, Fourier transform, and random number capabilities

Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

NumPy幾乎是一個無法回避的科學計算工具包，最常用的也許是它的N維數組對象，其他還包括一些成熟的函數庫，用于整合C/C++和Fortran代碼的工具包，線性代數、傅里葉變換和隨機數生成函數等。NumPy提供了兩種基本的對象：ndarray（N-dimensional array object）和 ufunc（universal function object）。ndarray是存儲單一數據類型的多維數組，而ufunc則是能夠對數組進行處理的函數。
