[Mike Miller]

Update of bug #38961 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #1:

Confirmed, but no I don't think it's a bug. The third argument to fplot gives
you control over how many points or how accurate the plot should be made. Your
second plot is slow because of the particular function you are evaluating and
the default tolerance of fplot, not simply because something was changed. If
you limit the plot to a fixed number of points you should see no change in
speed.


octave:1> fplot ("x^2*sin(x)+1", [-2, 2]);
octave:2> size (get (get (gca, "children"), "xdata"))
ans =
      1   1793
octave:3> fplot ("x^2*sin(x)+0", [-2, 2]);
octave:4> size (get (get (gca, "children"), "xdata"))
ans =
         1   1835009
octave:5> fplot ("x^2*sin(x)+1", [-2, 2], 2000), tic, print(1,
"a.png","-dpng"), toc
Elapsed time is 0.56231612 seconds.
octave:6> fplot ("x^2*sin(x)+0", [-2, 2], 2000), tic, print(1,
"a.png","-dpng"), toc
Elapsed time is 0.53061102 seconds.


Does that address the problem?
