The answer depends on the Matlab release you use. However,

• See Packaging AppsPackage and share your apps
• See matlab.codetools.requiredFilesAndProducts
• Search File Exchange for depfun
• See exporttozip by Mark Morehead
• See exportToZip: Identifies the dependencies of an M-file and creates a ZIP file by Malcolm Wood
• Search File Exchange for matlab.codetools.requiredFilesAndProducts

In the upper right corner of the title bar of the Current Folder panel, there is a little down arrow. You can click on it and select Reports -> Dependency Report.
