Specifications and Limitations

General Limitations

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

Product Limitations
  • MATLAB Online cannot interact with most other hardware, including instrument control.
  • Creating custom user interfaces, such as those built with GUIDE, is 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.
  • The graphical interface to the profiler is not supported.
  • Use of the shell escape bang (!) command is not fully supported.
Simulink Only some functionality through the command-line access to Simulink, via the sim command, is supported.
