4 Section Overview

Start current section content and materials

4.1 Introduction

This section introduces M-files in MATLAB, explaining their importance in executing and saving commands for repeated use.

4.2 M-File Scripts

M-file scripts in MATLAB are external files containing a sequence of commands that can be executed, making it easier to reuse and modify code.

4.2.1 Examples

This section details examples of creating and utilizing M-file scripts in MATLAB to solve equations and generate plots.

4.2.2 Script side-effects

This section explores the unintended consequences of using script files in MATLAB, particularly how they affect the workspace.

4.3 M-File functions

This section introduces M-File functions, explaining their structure, advantages over scripts, and their use in MATLAB programming.

4.3.1 Anatomy of a M-File function

This section introduces the basic components that make up an M-File function in MATLAB.

4.3.2 Input and output arguments

This section discusses the input and output arguments of M-file functions in MATLAB.

4.4 Input to a script file

This section describes how variables in a MATLAB script can be assigned values, focusing particularly on user input through the script.

4.5 Output commands

This section discusses the various MATLAB commands used to generate outputs, focusing on 'disp' and 'fprintf'.

4.6 Exercises

This section provides exercise problems for students to apply their knowledge of M-file scripts and functions in MATLAB.

Learning Objectives

  • Script files in MATLAB allow the execution of a series of commands repeatedly.

  • M-files can be either scripts or functions and have specific structures and uses.

  • Input and output handling is crucial for effective programming in MATLAB.

Key Concepts

MFile Scripts

External files containing a sequence of MATLAB statements, saved with a .m extension.

MFile Functions

Programs that accept input arguments and return output arguments, using a separate workspace.

Input Command

A command that prompts the user to enter values for variables during script execution.

Output Commands

Commands like disp and fprintf in MATLAB that generate displays or outputs from code.
