SciPy(Scientific Python)简介

SciPy(Scientific Python)是一个开源的Python算法库和数学工具包。它建立在NumPy的基础上,用于进行科学计算、数据分析和技术开发。SciPy库提供了许多用于优化、线性代数、积分、插值、特殊函数、快速傅里叶变换、信号处理和图像处理等模块。

入门SciPy,你可以按照以下步骤进行:

  1. 安装Python和SciPy

    • 确保你的计算机上安装了Python。你可以从Python官网下载并安装。
    • 使用pip安装SciPy:在命令行中输入pip install scipy
  2. 了解基础的NumPy库

    • 由于SciPy是建立在NumPy之上的,因此了解NumPy的基础操作是非常重要的。NumPy提供了多维数组对象和许多用于数组操作的函数。
  3. 阅读SciPy文档

    • SciPy的官方文档非常全面,是学习SciPy的好资源。你可以在SciPy官网找到文档。
  4. 学习SciPy的主要模块

    • SciPy包含多个模块,每个模块都专注于特定的任务。一些主要的模块包括:
      • scipy.integrate:数值积分。
      • scipy.linalg:线性代数。
      • scipy.optimize:优化和根查找算法。
      • scipy.signal:信号处理。
      • scipy.sparse:稀疏矩阵和稀疏线性代数。
      • scipy.special:特殊函数。
      • scipy.stats:统计分布和统计测试。
  5. 实践编程

    • 通过实际编写代码来解决具体问题,这是学习任何编程库的最佳方式。你可以从简单的问题开始,逐渐过渡到更复杂的任务。
Scientific Computing with Python 3 English | 23 Dec. 2016 | ISBN: 1786463512 | 332 Pages | AZW3/MOBI/EPUB/PDF (conv) | 17.95 MB Key Features Your ultimate resource for getting up and running with Python numerical computations Explore numerical computing and mathematical libraries using Python 3.x code with SciPy and NumPy modules A hands-on guide to implementing mathematics with Python, with complete coverage of all the key concepts Book Description Python can be used for more than just general-purpose programming. It is a free, open source language and environment that has tremendous potential for use within the domain of scientific computing. This book presents Python in tight connection with mathematical applications and demonstrates how to use various concepts in Python for computing purposes, including examples with the latest version of Python 3. Python is an effective tool to use when coupling scientific computing and mathematics and this book will teach you how to use it for linear algebra, arrays, plotting, iterating, functions, polynomials, and much more. What you will learn The principal syntactical elements of Python The most important and basic types in Python The essential building blocks of computational mathematics, linear algebra, and related Python objects Plot in Python using matplotlib to create high quality figures and graphics to draw and visualize your results Define and use functions and learn to treat them as objects How and when to correctly apply object-oriented programming for scientific computing in Python Handle exceptions, which are an important part of writing reliable and usable code Two aspects of testing for scientific programming: Manual and Automatic About the Author Claus Fuhrer is a professor of scientific computations at Lund University, Sweden. He has an extensive teaching record that includes intensive programming courses in numerical analysis and engineering mathematics across various levels in many different countries and teaching environments. Claus also develops numerical software in research collaboration with industry and received Lund University's Faculty of Engineering Best Teacher Award in 2016. Jan Erik Solem is a Python enthusiast, former associate professor, and currently the CEO of Mapillary, a street imagery computer vision company. He has previously worked as a face recognition expert, founder and CTO of Polar Rose, and computer vision team leader at Apple. Jan is a World Economic Forum technology pioneer and won the Best Nordic Thesis Award 2005-2006 for his dissertation on image analysis and pattern recognition. He is also the author of "Programming Computer Vision with Python" (O'Reilly 2012). Olivier Verdier began using Python for scientific computing back in 2007 and received a PhD in mathematics from Lund University in 2009. He has held post-doctoral positions in Cologne, Trondheim, Bergen, and Umea and is now an associate professor of mathematics at Bergen University College, Norway.
