What were you trying to do?
plot(v0,t=0.0..1.0);
(v0 is defined, along with a bunch of other stuff, in
~fmmoore/maple/bug-report; it's a maple user format file.)
plot(v0,t=0.0..0.4);
plot(v0,t=0.4..0.8);
What's wrong:
the plot from 0 to 1 is noncyclical; it's amplitude and
frequency seem to vary randomly. However, for the plots in the smaller
intervals, the amplitude and frequency of the wave are constant.
(postscript files of the plots are in ~fmmoore/maple/*.ps.F) I believe
that this isn't a problem of display resolution, because I stretched the
window horizontally a lot (about two screen widths), and it still
reflected the same problem.
What should have happened:
The plot of the large range should have reflected the
cyclicalness of the smaller ranges, or the smaller ranges should have
reflected the randomness of the large range; the smaller ranges should
be a subset of the larger range, no matter what the larger range looks
like.
Please describe any relevant documentation references:
none
