Please find the attached screenshot on the commands Benjamin suggested, and I am getting the same results that ST got:
octave:1:C:\> system (sprintf ("\"%s\" --version", gnuplot_binary ()))
gnuplot 4.3.0-2009-07-08 CVS patchlevel 0 octave-mingw32
ans = 0
octave:2:C:\> [status, output] = system (sprintf ("\"%s\" --version", gnuplot_binary ()))
error: value on right hand side of assignment is undefined
But I am quite sure I am running Win XP SP2 on a real hardware (and not as a virtual machine under virtualbox). Thanks in advance for any pointers.
Regards,
YF
