计算机中数据存储形式、形状(Shape)和步幅(Step)等信息;(2)NumPy中元素索引的用法,即通过索引能返回数组中满足特定条件的单个元素、子数组或元素;(3)NumPy强大的计算功能以及数组的向量化计算函数,如sum、mean和maximum等,以及 “广播”(broadcasting)规则。
NumPy是Python语言中主要的array编程库,在研究分析工作流程中扮演着根本性的角色,涵盖的领域包括物理、化学、天文学、地理、生物、心理学、材料科学、工程学、金融和经济等等。比如天文学,用于发现引力波以及获得第一张黑洞照片所涉及的软件栈中很重要的一部分就是NumPy。这里我们会梳理一下,它是如何从一些基础的array...

NumPyis a library for the Python programming language, adding support forlarge, multi-dimensional arrays and matrices, along with a large collection ofhigh-level mathematical functionsto operate on these arrays. 文章目录 一、多维数组 ndarray
The closest you can get to an array in Python is with the standard library’s array or NumPy’s ndarray data types. However, neither one of them provides a true array, as they can only hold numeric values. On the Real Python website, you’ll find tons of resources on NumPy if you...
Understanding Numpy Concatenate: Basic Use Thenumpy.concatenate()function is a powerful tool in Python, especially when working with arrays. It allows you to join two or more arrays along an existing axis. Let’s take a look at a basic example: ...
