Learning to Program with MATLAB Building GUI Tools

Introductory text integrating science, mathematics, and engineering to give a basic understanding of the fundamentals of computer programming with MATLAB

Learning to Program with MATLAB: Building GUI Tools, Second Edition serves as a compact introduction to computer programming using the MATLAB language, covering elements of both program and graphical user interface (GUI) design to enable readers to create computer programs just like the ones they are accustomed to interacting with. Rather than being encyclopedic in scope, the goal of the text is to describe what users will find most useful and point to other features. Descriptions and examples of some of the most useful functions are included throughout, particularly with regards to engineering and science applications. The work also includes updated videos and problem solutions on an instructor companion website.

The first edition of Learning to Program with MATLAB employed the MATLAB graphical user interface design environment (GUIDE) to develop the GUI tools. The second edition is based on the new and improved App Designer program, which has supplanted GUIDE. This edition includes:

• Core concepts of computer programming using MATLAB, such as arrays, loops, functions, and basic data structures
• How to write your own MATLAB functions, covering topics such as local workspaces, multiple outputs, function files, and other functional forms
• The new string class and table class, some new features of function arguments, and re-written sections for building GUI tools with App Designer
• Syntax for graphics and App Designer features, plus examples demonstrating the new way to handle string information

Starting with the basics and building up to an emphasis on GUI tools, Learning to Program with MATLAB is a comprehensive introduction to programming in a robust and multipurpose language, making it an ideal classroom resource for both students and instructors in related programs of study.
