What is an MLAPP file?

An MLAPP file is an application project created by The MathWorks MATLAB, a programming and numeric computing program for analyzing data, developing algorithms, and building models. It stores information about an app in the proprietary MATLAB App (MLAPP) format, including the layout of its visual components, the MATLAB code configuring the app's capabilities, and metadata. Examples of apps you might create and save as MLAPP files include a data visualizer for measuring and graphing blood sample data or a tool for measuring the different energy outputs of solar panels.

MATLAB is technical software that features a numerical computing environment and dedicated programming language. Engineers and scientists use MATLAB in various fields, including biological sciences, robotics, machine learning, wireless communications, risk management, and signal processing.

Among its many features, MATLAB provides an integrated development environment (IDE) that allows you to create apps. With this feature, you can design the layout and program the app's capabilities, then save it as an MLAPP file. When you want to share the app with other users, you can share it as an .MLAPPINSTALL file with other MATLAB users or compile it as a web or standalone desktop app.

How to create an MLAPP file with MATLAB

To create an MLAPP file with MATLAB:

  1. Select the APPS tab.
  2. Click Design App.
  3. Choose the layout you want to use.
  4. Select Save → Save or Save As.

After saving the file, you can close it and re-open it for further editing. When you finish developing the app, select Share from the DESIGNER tab, then choose to share it as an MLAPPINSTALL file or compile it as a standalone desktop app or web app.

How to open an MLAPP file

You can only open an MLAPP file with The MathWorks MATLAB (multiplatform). To open an MLAPP file, select the Apps tab, click Design App, then select Open.
