This example should respond more or less instantaneously.

Ok, let's turn on all output you can in order to troubleshoot this.
Make sure to do:

  setVerbose(matlab, -2)

before those non-responding calls.  You may also start the Matlab
server in a non-minimized window by calling:

  Matlab$startServer(minimize=FALSE)

This will allow you to see what the Matlab server is doing.  What do you get?

PS. Normally the above should work out of the box; I'm not sure why
you experience all these problems. DS.
