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.

Solving linear systems using matrices

A typical linear equation is expressed in the form of ax+by=c, where x and y are unknowns and a, b, and c are known values. Essentially, we are trying to find a relationship between a, b, and c.

There are multiple ways in which one is able to solve linear equations. In this recipe, we will be looking into the built-in function available in SciPy that helps us in solving a given linear system.

How it works…

The intuition behind solving for x and y is as follows:

([[a1 , b1 ], x ([x], = ([c1],
[a2 , b2 ]]) [y]) [c2])

For convenience, let's call the left-hand side matrix (a1, b1, a2, b2) the input matrix and the right-hand side matrix (c1, c2...
