read variables back into the program

[ClundXIII]

Hi,

I need to do a few (~ 650k) fits from within my program. Is it possible to automatically read the result back into a variable? Or should I rather use the higher-level interface for this case?

Regards,
Simon

No, this is not possible currently.  My interface doesn't currently have the ability to receive feedback back from gnuplot.  It is able to capture mouse clicks, but that works by telling gnuplot to send that info to a file (technically, a pty) and I read it from there. It would be feasible to add this feature, but it'd take some work.  Even if such a thing did work though, I think it'd probably be better to just do the fit from within your program (not through gnuplot) using some library designed for that purpose.  Any linear algebra package would make it easy to compute a linear fit, or even fit a linear combination of nonlinear functions, e.g., a polynomial.  For more general fitting, I know such a library exists but I can't remember the name of it. - Dan

Okay, thanks.
I will most likely use dlib for fitting. The curve is unfortunately not trivial.
