SciPy Recipes

By: V Kishore Ayyadevara, Ruben Oliva Ramos

Overview of this book

With the SciPy Stack, you get the power to effectively process, manipulate, and visualize your data using the popular Python language. Utilizing SciPy correctly can sometimes be a very tricky proposition. This book provides the right techniques so you can use SciPy to perform different data science tasks with ease. This book includes hands-on recipes for using the different components of the SciPy Stack such as NumPy, SciPy, matplotlib, and pandas, among others. You will use these libraries to solve real-world problems in linear algebra, numerical analysis, data visualization, and much more. The recipes included in the book will ensure you get a practical understanding not only of how a particular feature in SciPy Stack works, but also of its application to real-world problems. The independent nature of the recipes also ensure that you can pick up any one and learn about a particular feature of SciPy without reading through the other recipes, thus making the book a very handy and useful guide.

Defining, symbolically, a function operating on arrays

Anybody that has written numerical code will know that a common source of mistakes is the definition of functions that evaluate a complicated formula. One way around this problem is to use a package for symbolic computations, and we will take advantage of sympy, which is a compact Python symbolic package.

Getting ready

If you are using Anaconda, sympy is already installed on your system. Otherwise, you will have to install it by using pip3 install sympy.

To see the full results of the following recipe, we assume that the reader is running Jupyter. Before getting started, run the following code in a Jupyter cell:

from sympy import *
init_printing(use_latex=True)
