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.

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 Add “%” at the end of the code to be commented 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 do not want these points to be executed by the MATLAB compiler and so will “comment” them. 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. 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. For complex values of X, sin (X) returns complex values. For real values of X, sin (X) returns real values in the interval -1, 1. The function accepts both real and complex inputs. The sin function operates element-wise on arrays. 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. Y sin (X) returns the sine of the elements of X. 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. This event demonstrated the potential of MathWorks. Write the code along with the explanation pointsĢ. MathWorks celebrates RVITM for its exceptional use of MATLAB at the Journey to Success event. We do not want these points to be executed by the MATLAB compiler and so will “comment” them. We will write a dummy code and will give some points explaining this code. In this example, we will use the “Comment” button in the Live Editor of MATLAB to comment a block of code. Alternatively, you can specify the vector of frequencies at which you want to compute the transform, as in this example. However, for one-sided transforms, which are the default for real signals, spectrogram uses 1024 / 2 + 1 513 points. Let us discuss examples of Matlab Block Comment. You can specify this number if you want to compute the transform over a two-sided or centered frequency range.
