![]() 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. Alternatively, select the code and type 'Ctrl' + 'R'. This inserts a '' symbol in front of each selected line. We have done this by pressing together “Ctrl” and “R” keys.ġ. Best Answer 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. a string of text that begins with a symbol is ignored by the Matlab compiler. There is a space after a percentage symbol. It always starts with a percentage () symbol character and ends with a line break. It can be added as newline or existing code lines as inline code. The output will be remainder of 33/5 i.e 3Īs we can see in the output, the explanation points are now commented on. Single-line comments are always written in a single line. Mod function gives remainder as the output 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 We must “comment” these two lines to avoid the error. 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: Initializing 5 normally distributed numbersĢ. 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. I want to replace names of the data store memory, data store write, data store read used in my simulink model. In this example, we will use the “Comment” button in the Live Editor of MATLAB to comment a block of code. Commented: Sandesh Achari on Accepted Answer: Maverick I am using MATLAB 2014b. Matlab compiler ignores the text after the ellipse msg = ['Welcome to'.Let us discuss examples of Matlab Block Comment. Matlab multiline commentĮllipse(…) is used to add the comment text in multi-lines. You can also nest a block comment inside another block comment. Multi-line comments starts with % string span in multiple linesīasic program to print hello world to console These comments are written in multiple lines and are also called block comments. These comments contain comment text span in multiple lines. Learned single line comments, How do you write a multi-line comments. Hello.mlx % This is a simple hello world program in matlab Syntax: % These are single-line comments in the Matlab file These comments are not required at the start at the beginning of the line, but also can write in the middle or end of the line.It is a description or piece of text for a single line of code.a string of text that begins with a % symbol is ignored by the Matlab compiler.There is a space after a percentage symbol.It always starts with a percentage (%) symbol character and ends with a line break. ![]() ![]() Single-line comments are always written in a single line. It is always good to practice adding comments to the code for better readability and maintenance of Matlab Comments Single line In Matlab, You can write a comment in different following ways. Generally, Comments are for programmers not for a compiler. Comments are statements to describe code. ![]()
