Re: how to apply gnuplot_fixed to octave 2.9.16 MSVC

[Tatsuro MATSUOKA]

Dear all

After the mail, Michael and I personally exchanged the mails.
Michael kindly tried the addtional fix and I tested it in my computer.
It worked well.


So this problem will be solved in the next release.
For those who cannot execute the gnuplot in the gnuplot_fixed.zip, please wait 
the next release.

I here again appreciate Michael for his efforts.

I think that this thread is to be ended here.
