Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “To create a classification tree, we can utilize the fitctree() function.”

A block of code is set as follows:

gscatter(meas(:,3), meas(:,4), species,'rgb','osd');
xlabel('Petal length');
ylabel('Petal width');

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Now, we can train the network just by clicking on the train button of the app. After a few seconds, the ANN will be trained and ready for use.”
