MATLAB® provides options for presenting your code to others, including using publishing and creating live scripts and functions in the Live Editor.
The easiest way to create cohesive, sharable documents that include executable MATLAB code, embedded output, and formatted text is to use the Live Editor. Supported output formats include: MLX, PDF, Microsoft® Word, HTML, and LaTeX. For details, see Create Live Scripts in the Live Editor.
Publishing a MATLAB Code file (
.m) creates a formatted document that
includes your code, comments, and output. Common reasons to publish code are to
share the documents with others for teaching or demonstration, or to generate
readable, external documentation of your code.
This code demonstrates the Fourier series expansion for a square wave.
MATLAB Code with Markup
To publish your code:
Create a MATLAB script or function. Divide the
code into steps or sections by inserting two percent signs (
at the beginning of each section.
Document the code by adding explanatory comments at the beginning of the file and within each section.
Within the comments at the top of each section, you can add markup that enhances the readability of the output. For example, the code in the preceding table includes the following markup.
Variable name in italics
When you have a file containing text that has characters in a different encoding than that of your platform, when you save or publish your file, MATLAB displays those characters as garbled text.
Publish the code. On the Publish tab, click Publish.
By default, MATLAB creates a subfolder named
html, which contains an HTML
file and files for each graphic that your code creates. The HTML file includes the code,
formatted comments, and output. Alternatively, you can publish to other formats, such as
PDF files or Microsoft
PowerPoint® presentations. For more information on publishing to other formats, see
Specify Output File.
Online™, MATLAB publishes to either HTML or PDF, and stores the output and supporting
files in your
Published folder. To allow MATLAB to open the output automatically, enable pop-up windows in your Web
browser. Results are available publicly using a URL of the form
(for HTML) or
The sample code that appears in the previous figure is part of the installed documentation. You can view the code in the Editor by running this command:
edit(fullfile(matlabroot,'help','techdoc','matlab_env', ... 'examples','fourier_demo2.m'))
You can add help to your code by inserting comments at the start of a MATLAB code file. MATLAB displays the help comments when you type
file_name in the Command Window. For more information,
see Add Help for Your Program.
You also can create your own MATLAB documentation topics for viewing from the MATLAB Help browser or the web. For more information, see Display Custom Documentation
