The selected comment lines are reformatted so that no comment line in the selected area is longer than the maximum. Use an arrow pointing to the right instead of to the left. This examples shows some lines of code commented out. For Comment formatting, set the Max width.
This is useful when you want to identify the section of a file that is not working as expected. For a single line, position the cursor in that line. The help system ignores any comment lines that appear after the help text block.
Lines that were shorter than the specified maximum are merged to make longer lines if they are at the same level of indentation. Each element of the cell array is one line of text. You can comment the current line or a selection of lines: The first help text line, often called the H1 line, typically includes the program name and a brief description.
You can return the Text object as an output argument from the text function and assign it to a variable, such as t. Use the Text object. This example shows how to add text to a chart, control the text position and size, and create multiline text. The following example comments out the Middle Initial line.
See also sum, plus.
You can use a similar approach to change the font size when using the title, xlabel, ylabel, or legend functions. Then, use dot notation to set properties, such as t. The Current Folder browser and the help and lookfor functions use the H1 line to display information about the program.
This is machine translation Translated by Mouseover text to see original. For example, create a function in a file named addme. For this example, display a title with two lines. To uncomment the current line or a selected group of lines, select Uncomment from the Text menu, or right-click and select it from the context menu.
Note When multiple programs have the same name, the help command determines which help text to display by applying the rules described in Function Precedence Order.
MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation. For this example, calculate the average y value and include the value in the title.
This page has been translated by MathWorks. The second input argument specifies the position of the annotation in units normalized to the figure. The third argument specifies the text.
Within the anchor, use a matlab: To comment out text within a multiline statement, use the ellipsis You can set properties in two ways: Commenting Out Part of a Statement.
The first two input arguments to the text function specify the position. Help text appears in the Command Window when you use the help function.I need to plot a few points in a graph and then write a comment next to each point. How can I do this? I plotted the points like this plot(,'o') hold on; plot(,'o') p.
How do I comment out a large block of code in MATLAB? Asked by Doug Hull. Doug Hull (view profile) 29 questions asked; answers; 96 accepted answers; and write whatever you want. This will enable you to write a very long comment line.
For example * This is a very very long comment 0 Comments. Show Hide all comments. Sign in to comment. To comment out the end of a statement, put the comment character, %, before the comment.
When you run the file, MATLAB ignores any text on the line after the %. To comment out text within a multiline statement, use the ellipsis. Comment lines begin with the character '%', and anything after a '%' character is ignored by the interpreter. 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. Run the command by entering it in the MATLAB Command Window. Web browsers do not support MATLAB commands.
Close ×. Add Comments to Programs. When you write code, it is a good practice to add comments that describe the code. Add comments to MATLAB ® code using the percent (%) symbol. Comment lines can appear anywhere in a program file, and you can append comments to the end of .Download
