You can use MATLAB®  to evaluate expressions written in MATLAB syntax in Cameo Simulation Toolkit. You must install MATLAB® first and set up your system to call and use it in Cameo Simulation Toolkit. 

Note

  • For successful integration, you must use either the 64-bit or 32-bit version of MATLAB (Version 2012a or later) to align it with the 64-bit or 32-bit version of modeling tools, e.g., MagicDraw or Cameo Systems Modeler.
  • For Mac users, Cameo Simulation Toolkit version 18.5 SP2 and later can integrate with MATLAB® 2016b seamlessly without disabling System Integrity Protection (SIP) unless it is necessary to disable SIP as a new feature of the latest OS X El Capitan for successful integration.

Warning

MATLAB® 2014a on Mac OS is not capable of evaluating and returning values via Simulation Console, which causes MagicDraw to freeze. To solve this problem, please consider upgrading MATLAB® 2014a to 2014b or later.


To disable OS X El Capitan's System Integrity Protection (SIP)

  1. Restart your Mac.
  2. As soon as the screen turns black, hold down the command+R keys to access the Recovery Partition.
  3. Release the keys once the Apple logo appears on your screen.
  4. Click the Utilities menu and select Terminal.
  5. Type csrutil disable into the Terminal window and press Return.
  6. The Terminal should display a message that SIP was disabled.
  7. Restart your Mac for the changes to take effect.
  8. Run MagicDraw/Cameo System Modeler and integrate it with MATLAB®.
