Was Running Beautifully, Now Not?

[Damian Harty]

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:

       --nostringval--

    Execution stack:

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

    Dictionary stack:

    Current allocation mode is local

    Last OS error: No such file or directory

    GPL Ghostscript 9.07: Unrecoverable error, exit code 1

 

The script runs and does everything it is supposed to.

 

I tried the only thing I know, to swap the graphics toolkit from fltk to gnuplot, but that didn’t help.

 

The lines in the script that generate the difficulty are

 

print(1,'roll_rate.jpg')

print(2,'fitted.jpg')

 

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…
