Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_create_buffer”.

  FT_CREATE_BUFFER starts the thread with the TCP server attached to the local
  MATLAB instance. The TCP server will listen to the specified network
  port, and accept incoming read and write requests.
 
  Use as
    ft_create_buffer(port)
  where port is the TCP port to which the server listens. The default port 
  number is 1972.
