There are two useful keyboard shortcuts for adding and removing chunks of comments. In the MATLAB Editor, commented areas are printed in green by default, so they should be easy to identify. The % character itself only tells the interpreter to ignore the remainder of the same line.

Octave/MATLAB differencesĬomment lines begin with the character '%', and anything after a '%' character is ignored by the interpreter. This is like having a personal assistant who takes notes for you while you're busy coding.Chapter 1: MATLAB Introductions. Moreover, you can use comments to generate documentation for your code. It's like playing a game of 'whodunit' with your code. By commenting out sections of your code, you can isolate the parts that are causing trouble. Advanced Commenting TechniquesĬomments can also be used for more than just explaining your code. This comment tells us the why, not just the what. Instead, a better comment would be: x = x + 1 % Prepare x for the next iteration It's like saying, "And on your right, you'll see the Eiffel Tower" when you're standing right under it. The comment here is like a tour guide stating the obvious. Consider this line of code: x = x + 1 % Increment x by 1 An outdated comment is like a map to a treasure that's already been moved. It's like a detective novel, where the code is the evidence and the comments are the detective's deductions. Your code tells the what, your comments should tell the why. Just like you wouldn't paint a masterpiece with a single color, you shouldn't comment your code haphazardly.įirstly, use comments to explain the why, not the what. Now that we've covered the basics, let's talk about the art of commenting. It's like putting a big, invisible cloak over your code. These are the granddaddies of the comment world, used to comment out large chunks of code. Think of it as creating a cozy little home for your comment, where it can sit comfortably, away from the prying eyes of the MATLAB interpreter.Īnd then there's block comments. It's like saying "psst" to MATLAB, telling it to ignore everything that follows on that line.įor multi-line comments, you'll need to use the % symbols to start and end your comment, respectively. For single-line comments, simply use the percent symbol % at the start of your comment. How To Add Comments In MATLABĪdding comments in MATLAB is as easy as pie, and much less messy. They're like the three musketeers of code clarity, each with their own unique strengths. There are three types of comments you can use to annotate your MATLAB code: single-line, multi-line, and block comments. In MATLAB, comments are the translator that turns alien into familiar, making your code understandable not just to others, but to your future self as well. Frustrating, isn't it? That's what it's like to read code without comments. Imagine you're reading a gripping novel, but every now and then, you come across a sentence written in an alien language.
