Want to allow in a line of comments, and then select where you want counting to begin.Consider selecting: Start from beginning of line when the absolute width of the comments is important. For example, set 75 columns from the start of the line to match the width that fits on a printed page when you use the default font for the Editor. Start from beginning of comment when comments are indented, and you want each block of comments to have a consistent indent and width.Select Wrap comments automatically while typing to automatically wrap comments at the Maximum column width value when you type comments in an Editor or Live Editor document. If you clear this option, you can still wrap comments manually, as described in Add Comments to Code.IndentingSelect Apply smart indenting while typing to automatically:Indent the body of loops within the start and end of the loop statement.Align subsequent lines with lines you indent using tabs or spaces.Indent functions as specified with the Function indenting format option. You also can manually apply automatic indenting after you type the code. For more information, see Indent Code.Select an option from Function indenting format (MATLAB Language only) to specify how functions indent in the Editor and Live Editor, as follows:Classic — The Editor and Live Editor align the function code with the function declaration. Indent nested functions — The Editor and Live Editor indent the function code within a nested function.Indent all functions — The Editor and Live Editor indent the function code for both main and nested functions.File extensionsAdd one or more file extensions to associate with the Language. The preferences you set for that language apply to all files with the listed extensions.Editor/Debugger Code Folding PreferencesCode folding enables you to expand and collapse blocks of MATLAB code that you want

You can customize the visual display and functionality of the Editor, Live Editor, and Debugger using Editor/Debugger preferences.General Preferences for the Editor/DebuggerYou can specify which editor MATLAB® uses, as well as how the MATLAB Editor and Live Editor behave under various circumstances.On the Home tab, in the Environment section, click Preferences. Select , and then adjust preference options as described in the table below.Some general preferences are not available in MATLAB Online™. PreferenceUsageEditorSelect which editor you want the MATLAB desktop to use when you edit a file:MATLAB EditorText editorIf you select Text editor, specify the full path for the editor application you want to use, such as Emacs or vi. For example, c:/Applications/Emacs.exe.This preference applies only to plain text files such as files with a .m or .txt extension.Most recently used file list In the Number of entries field, type the number of files that you want to appear in the list of recently used files at the bottom of the File menu.Opening files in editorSelect On restart reopen files from previous MATLAB sessions if you want the Editor and the files it contained during your last MATLAB session to reopen when you restart MATLAB.Select Automatically open files when MATLAB reaches a breakpoint to open a running program file when MATLAB encounters a breakpoint in that file.Select Display full path of files in the Editor to display the full path of files open in the MATLAB Online Editor and Live Editor. The path displays at the top of each open file.Automatic file changesSelect Save changes upon clicking away from a file if you want the Editor and Live Editor to automatically save changes to a file when you click away from the file. For the changes to be automatically saved upon clicking away, you must have already saved the file

Mermaid Editor is VSCode extension inspired by official mermaid live editor which provides mainly the following features:Live edit mermaid.js diagram file with mermaid.js diagramGenerate image file from mermaid.js diagram file with preferred format (png, jpg, webp and svg).Copy image to clipboard directly.Customize configuration for individual mermaid.js diagram by using atrribute which is available in this extension.Mermaid Editor does not contain syntax highlighting for Mermaid charting language.But don't warry, a great plugin Mermaid Markdown Syntax Highlighting works with Mermaid Editor.Mermaid Editor is also available on Open VSX Registry for developers who love FLOSS binaries of VSCode.Mermaid Editor is implemented as 100% local solution mainly using mermaid.js and VSCode SDK.It means Mermaid Editor does NOT require online environment and NOT send your code to any remote server in order to work.Enjoy!UsageThis VSCode extension is activated when opening .mmd or .mermaid file.

Main Content Create self-contained apps, embedded Live Editor tasks, and custom UI components MATLAB® provides functions and tools to build interactive user interfaces. You can add components, such as buttons and sliders, to enable user interaction and include plots for data visualization and exploration in these interfaces. To create self-contained interfaces that perform operations based on user interactions, develop apps. To create interfaces that can be embedded into a live script and that generate code as users explore parameters, develop Live Editor tasks. For more information, see Ways to Build Apps. A large set of UI components are available for creating interfaces in MATLAB. You also can extend the list of available components with your own specialized UIs and visualizations by creating custom UI components.
