ok, you're running 2.9.14 which is not the current release. I don't have a copy of the 2.9.14 manual, but since surfc was added to Octave's sources in November 2007 and we are currently at 3.0.1, it is likely that surfc is not present in 2.9.14.

Please download the most recent sources and compile/install those.
