Statement (if those lines do not already contain a section break). MATLAB adds section breaks at the lines containing the start and end of the In the Editor, if you add a section break within a loop or conditional statement Behavior of Sections in Loops and Conditional Statements Script, you can run only the sections that are before the local functionĭefinitions. When running individual sections in a live Script, MATLAB adds a section break before the first local function definition and Inside local functions are not supported. In the Live Editor, you cannot add section breaks inside a function. Statement, MATLAB behaves as if the end of the function occurs immediately before the If you do not end the function with an end In the Editor, if you add a section break within a function, MATLAB inserts section breaks at the function declaration and at the functionĮnd statement. MATLAB runs the section after every click. Then, click one of the operator buttons to add to, subtract from, multiply, orĭivide the selected value in your section. In the dialog box that appears, specify a step valueįor addition and subtraction or a scale value for multiplication and division. Next, right-click and select Increment Value and To adjust a numeric value, select the value or place your cursor next to the Workflow can help you fine-tune and experiment with your code. Values within a section, rerunning that section after every change. In the Editor, you can increment, decrement, multiply, or divide numeric Information, see Debug MATLAB Code Files. In functionsĪvailable only when evaluation is paused. In the Live Editor,Īvailable for all code, whether it is saved or not. MATLAB continues running until the end of the file isĪvailable only for code that has been saved. Run to a specific line of code and pause. Run the code in the selected section, and then run all the code Run the code in the selected section, and then move to the next This table describes different ways to run your code. When running individual sections, MATLAB does not save your file and the file does not have to be on your To run a section individually, it mustĬontain all the values it requires, or the values must exist in the MATLAB workspace. Running all of the code in the file at once. You can run your code file by either running each section individually or by The gray area to the left of your code and clear the Show Run Section To hide one or more of the margins, right-click This minimizes the grayĪrea to the left of your code. The Run Section, Run to Here, and Code Folding margins. To maximize the space available for editing code in the Editor, you can hide For more information about when MATLAB might add a section break, see Behavior of Sections in FunctionsĪnd Behavior of Sections in Loops and Conditional Statements. Here we discuss introduction, syntax, and how to comment a block of code in MATLAB with examples.You cannot remove sections breaks added by MATLAB. 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 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. In this example, we will use the “Comment” button in the Live Editor of MATLAB to comment a block of code. Let us discuss examples of Matlab Block Comment.
