6. Debugging M-files

The chapter delves into debugging techniques for M-files, focusing on identifying and correcting errors. It outlines the process of debugging, including preparing for debugging, setting breakpoints, running M-files, examining values, and making corrections. Additionally, it emphasizes the importance of ending a debugging session properly and the steps required to correct errors within an M-file.

Sections

Debugging M-files

This section covers the fundamental techniques for debugging M-files in MATLAB, including identifying and correcting syntax and run-time errors.

6 Section Overview

Start current section content and materials

6.1 Introduction

This section provides an overview of debugging techniques for M-files, introducing types of errors and their resolution.

6.2 Debugging process

The debugging process in MATLAB helps identify and fix errors in M-files using the Editor/Debugger and debugging functions from the Command Window.

6.2.1 Preparing for debugging

This section provides essential steps for preparing to debug M-files using the MATLAB Editor/Debugger.

6.2.2 Setting breakpoints

Setting breakpoints allows a programmer to pause code execution for debugging purposes.

6.2.3 Running with breakpoints

Running M-files with breakpoints enables the programmer to pause execution, allowing for examination of variables and control of program flow in MATLAB.

6.2.4 Examining values

This section discusses how to examine variable values during debugging in M-files using MATLAB.

6.2.5 Correcting and ending debugging

This section discusses how to correct errors in M-files during a debugging session and how to properly end the debugging process.

6.2.6 Ending debugging

The section outlines the proper way to conclude a debugging session in MATLAB after identifying and resolving issues.

6.2.7 Correcting an M-file

This section outlines the steps to correct errors in M-files after debugging.

Learning Objectives

  • Debugging involves isolating and fixing errors in M-files.

  • Two main types of errors are syntax errors and run-time errors.

  • Utilizing the Editor/Debugger effectively expedites the debugging process.

Key Concepts

Debugging

The process of identifying and resolving errors in a program or code.

Breakpoints

Markers set in the code to pause execution and examine variables.

Runtime Errors

Errors that occur while a program is running, which can lead to unexpected results.

Syntax Errors

Errors caused by incorrect syntax that prevents the code from running.
