O Learned Denizens,


A previously flawless-running M file now throws out this message when it gets to the printing bit:


    Error: /undefined in nan

    Operand stack:


    Execution stack:

      %interp_exit   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--

    GPL Ghostscript 9.07: Unrecoverable error, exit code 1

The lines in the script that generate the difficulty are





Without them, no messages. Obviously no files, either.


Windows 7 64 Bit, Octave 3.6.4. No known recent changes.


Given that it works, I’m not *too* worried. But it’s a load of spam I don’t want. And I want other people to use this code too, so my pride is at stake…
