Hi,
could you send me what Matlab is outputting. When I send the following from R:
> evaluate(matlab, "A=2;");
Sending expression on the Matlab server to be evaluated...: 'A=2;'
and Matlab should print something like:
Received cmd: 1
"eval" string: "A=2;"
Received an 'OK' reply (0) from the Matlab server.
Evaluated expression on the Matlab server with return code 0.
Sent byte: 0
I'm really interested to see what that "eval" string line looks like
just before you get the error.
/Henrik
