#### 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.

## Setting up the system

To access the Preferences dialog, you need to select Edit | Preferences… in the application menu.

### Note

On Mac OS X, the Preferences menu is located in the Mathematica application menu.

Let's review the most interesting settings of the system, which will be useful for our further work:

In the Appearance | Number | Formatting tab, you can select various numeric formatting options. Will there be a space separator between the digit blocks? What should be the decimal point character? How many digits will be displayed by default in the output?

In the next Multiplication tab, you can select the appearance of the multiplication:

### Note

In Mathematica, the space between two expressions means multiplying those expressions.

In this tab, you can choose whether the multiplication symbol between the multiplied numbers appears automatically, as well as choose the symbol type: space, center dot, *, or x.
