A MATLAB® app installer file, .mlappinstall, is an archive file for sharing a MATLAB GUI as an app. A single app installer file contains everything necessary to install and run an app, including source code, supporting data, information (such as product dependencies), and the app icon.
An .mlappinstall file is a compressed package that conforms to the Open Packaging Conventions (OPC) interoperability standard. You can search for and install .mlappinstall files using your operating system file browser. When you select an .mlappinstall file in Windows® Explorer or Quick Look (Mac OS), the browser displays properties for the file, such as Authors and Release. Use these properties to search for .mlappinstall files. Use the Tags property to add custom searchable text to the file.
