starts the external program prog and opens a MathLink connection to it.
  • LinkLaunch["prog"] runs prog as a subsidiary or child process to your current Mathematica session.
  • You can use a command such as LinkLaunch["math -mathlink"] to launch a subsidiary Mathematica kernel process from within your Mathematica session.
  • On most computer systems calling LinkLaunch["prog"] multiple times with the same argument will start several prog processes running.
  • On some computer systems, LinkLaunch[] will bring up a program browser.
  • The option LinkProtocol specifies the underlying data transport protocol to use.
  • LinkLaunch internally calls a function analogous to the MLOpenArgv() function in the MathLink library.
