Dear All,

I have a problem with the octave to gnuplot interface:

in an octave script I generate several gnuplot plots, export them to postscript and do some postprocessing on the resulting eps files with a awk script that is started via system statements from octave. Now it seems that octave does not wait for gnuplot to finish the individual plots. So at some point in the octave script, octave starts the awk postprocessor on an eps file that has not been generated yet. My workaround has been sleep statements between the plotting and the postprocessing commands in the script. However, depending on the number and complexity of the plots it can take up to several seconds for gnuplot to catch up. Obviously, I would not like to add "sleep(10)" to all my plot sequences just to make sure.

My question: is there a way to actively synchronize octave with gnuplot, i.e. force octave to wait until gnuplot has finished a particular plot command?

Thanks in advance

Thorsten Meyer
