Such text is often found at the end of an M file though also can be found at the beginning. MATLAB will output the comments leading up to the function definition or the first block of comments inside a function definition when you type:Īll of MATLAB's own functions written in MATLAB are documented this way as well.Ĭomments can also be used to identify authors, references, licenses, and so on.

It is common and highly recommended to include as the first lines of text a block of comments explaining what an M file does and how to use it. % Calculate average velocity, assuming acceleration is constant Doing this is a good idea both for yourself and for others who try to read your code.

E.g.Ĭomments are useful for explaining what function a certain piece of code performs especially if the code relies on implicit or subtle assumptions or otherwise perform subtle actions. */ in languages like C or C++, via the % contains any other text (except white spaces). MATLAB also supports multi-line comments, akin to /*. Select the code you wish to comment or uncomment, and then press Ctrl-R ( ⌘-/ for Mac) to place one '%' symbol at the beginning of each line and Ctrl-T ( ⌘-T for Mac) to do the opposite. 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. Select the code you wish to comment or uncomment, and then press Ctrl-R ( -/ for Mac) to place one '' symbol at the beginning of each line and Ctrl-T. The % character itself only tells the interpreter to ignore the remainder of the same line. In the MATLAB Editor, commented areas are printed in green by default, so they should be easy to identify.
