Here we discuss introduction, syntax, and how to comment a block of code in MATLAB with examples. There are various ways in which we can comment a block of code in MATLAB Recommended Articles This is usually done to provide the explanation of the code without interfering with the compilerģ. Block comment is used in MATLAB if we want to prevent a particular block of code from getting executedĢ. We have done this by pressing together “Ctrl” and “R” keys.ġ. Ive built a Simulink model and I would like to Comment Through some blocks via a MATLAB script. The output will be remainder of 33/5 i.e 3Īs we can see in the output, the explanation points are now commented on. Mod function gives remainder as the output As Matlab only has single line comments, to mark an entire region as a comment (called a block comment) use the single line comment over and over again. Add “%” at the end of the code to be commented We do not want these points to be executed by the MATLAB compiler and so will “comment” them. Here also we will write a dummy code and will give some points explaining this code. In this example, we will use the “%” key in our keyboard to comment a block of code. Here we have commented them by using the “Comment” button in the Live Editor of the MATLAB Example #2 To uncomment the selected text, click the 'Uncomment' button. Alternatively, select the code and type 'Ctrl' + 'R'. This inserts a '' symbol in front of each selected line. We must “comment” these two lines to avoid the error. To comment out a large block of code in the Editor or Live Editor, select the code and on the 'Editor' or 'Live Editor' tab, click the 'Comment' button. If we execute our input directly, MATLAB will throw an error for line 3 & 4 as these lines are in human-friendly language and not understood by the MATLAB compiler. Output (After commenting the block of code): This is how our input and output will look like in MATLAB: And see 3 ways to quickly add numbers, too. Initializing 5 normally distributed numbersĢ. Training: Use Excel Online to change the formatting of numbers and text to help make your information stand out. Click on the “Comment” button (represented as a “%” sign) present in the “Live Editor” tab as shown belowġ. Select the block of code which you want to comment (points written as explanation)ģ. Write the code along with the explanation pointsĢ. We will write a dummy code and will give some points explaining this code. These comments are intended to convey the intentions of several lines of code (that is, a block of code - hence the name block comments). In this example, we will use the “Comment” button in the Live Editor of MATLAB to comment a block of code. Error Rate Calculation Block, requires the. Let us discuss examples of Matlab Block Comment. Matlab Comment BlockCommenting Through a Simulink block semmingly changes the response of an unrelated system.
