#### Overview of this book

There are many algorithms for data analysis and it’s not always possible to quickly choose the best one for each case. Implementation of the algorithms takes a lot of time. With the help of Mathematica, you can quickly get a result from the use of a particular method, because this system contains almost all the known algorithms for data analysis. If you are not a programmer but you need to analyze data, this book will show you the capabilities of Mathematica when just few strings of intelligible code help to solve huge tasks from statistical issues to pattern recognition. If you're a programmer, with the help of this book, you will learn how to use the library of algorithms implemented in Mathematica in your programs, as well as how to write algorithm testing procedure. With each chapter, you'll be more immersed in the special world of Mathematica. Along with intuitive queries for data processing, we will highlight the nuances and features of this system, allowing you to build effective analysis systems. With the help of this book, you will learn how to optimize the computations by combining your libraries with the Mathematica kernel.

## Chapter 1. First Steps in Data Analysis

Wolfram Mathematica is not just a system that can solve almost any mathematical task. It is a Swiss army knife, which allows you to process images, audio, and written text to perform classification and identification of objects, as well as to manage files. It also provides other tremendous capabilities. In Mathematica, you can call functions, as well as receive a call from modules that are written using different programming languages and technologies, such as C, .NET, Java, and others. The system can generate code and compile files. Mathematica includes over 4,500 functions, which go beyond mathematical calculations. Wolfram Mathematica is constantly changing while still maintaining full compatibility with previous versions.

In this chapter, you will learn the following:

• How to install the Wolfram Mathematica system

• How to configure it to fit your needs

• What the Wolfram language kernel is and how to run it

• Wolfram Mathematica features to write expressions
