Mathematica Data Analysis

By: Sergiy Suchok

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.

Importing data from Mathematica's notebooks


In Mathematica, it is very convenient to transfer the formulas that you have used in other notebooks. This is done using the ImportNotebook function.

For example, let's create a new document using the CreateDocument function:

We have created a document in which there are only two cells to calculate—the root of 16 and the root of -6. This is a test example to demonstrate the function's capabilities. As a result, we get the following notebook:

Let's consider import options with the help of the NotebookImport function. In order to import all the notebook's parameters, just call NotebookImport with the "_" parameter:

In order to convert the values to text, you can use the _->"Text" rule:

Note

Arrows and double square brackets are input with the help of the following combination of keys: Esc - >Esc.

Let's use the "Input" parameter to get a list of cells with input data:

To import only the computed cells, you need to use the "Input" -> "InputText"...
