I am working on a project based on image processing using matlab. I want to know how to take a value generated in matlab workspace to outside via serial port so that I can control a system using the generated value. Also please tell me is there any other method other then using the serial port.

There are a number of other methods of communication of values for controlling something. Some of them include:
  • traditional hard-wired ethernet
  • "firewire"
  • USB
  • "thunderbolt"
  • WiFi
  • BlueTooth
  • NFC
  • encode the data as sound and send it to an audio port
  • get a DAQ (Digital / Analog convertor)
  • parallel port (not recommended for new projects)
  • get a signal generator and communicate with it using one of the above
