Web App Limitations and Unsupported Functionality
When packaging a MATLAB® app into a web app consider the following functional limitations. Using certain functions may result in an error or unexpected behavior.
Because a deployed web app is hosted on a server, functions that use system information have access only to server-side information, not client-side information. In addition, the web app is displayed in a browser window as opposed to a separate figure window. As a result, certain functions and properties behave differently in a deployed web app than on your local system. This table lists some of the differences that are most relevant to app building workflows.
