#### 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.

## Interface implementation with a program in С/С++

Let's consider how a C program should be prepared in order to make the WSTP protocol interaction available.

Firstly, as mentioned in the previous chapter, you need to prepare a special tm file that will describe all the data that will interact with Mathematica.

Secondly, the source code written in C should include the standard WSTP header file:

`#include "wstp.h"`

### Note

This file is located in the `C:\Program` `Files\Wolfram` `Research\Mathematica\10.1\SystemFiles\Links\WSTP\DeveloperKit\Windows-x86-64\CompilerAdditions\mldev64\include` folder.

This file defines the following types:

 WSLINK A WSTP link object (analogous to LinkObject in the Wolfram Language) WSMARK A mark in a WSTP stream WSENV The WSTP library environment

All functions that return the `int` type—`return` `0` if their execution is not successful.

Thirdly, the external program should be ready to receive instructions from the Mathematica environment; that's why the main function must have the...
