Specifications and Limitations

General Limitations

The following MATLAB and Simulink features and commands are not supported in MATLAB Online:

Product Limitations
  • MATLAB Online connects to a remote session running on a Linux system.
  • MATLAB Online cannot interact with some hardware, including instrument control.  Hardware that can be accessed include:
  • Packaging tools for add-ons and MATLAB Compiler and MATLAB Compiler SDK are not supported.
  • Windows-specific components like COM are not supported. 
  • xlsread and xlswrite will work in basic mode.
  • Using the MEX command to build C/C++ or Fortran MEX-files is not supported.
  • Files larger than 256 MB cannot be uploaded on MATLAB Online, but can be through MATLAB Drive.
  • The graphical interface to the profiler is not supported.
  • Use of the shell escape bang (!) command is not fully supported.

Most Simulink features, including editing and simulating models, are supported.

Simulink Online can communicate with Raspberry Pi hardware - external mode is not supported.

Simulink Online can communicate with Parrot Minidrone hardware - deployment is not supported.

Features that are not supported:

  • Variant Manager
  • Simulink Debugger

Other Simulink Online limitations:

  • Only Windows® keyboard shortcuts are supported
  • Screen resolutions larger than 1920x1200 are not supported
  • Users of Simulink Online outside of the US may experience slow performance.
