- GrafEq, a grapher
which uses interval arithmetic
"... GrafEq uses interval arithmetic
to plot: it checks a 2-dim rectangle
to see if there are any solutions in it - if so, it sub-divides the
rectangle & checks for solutions etc etc.... it ends up as a collection of 1
pixel rectangles. Use: provides more valid results than typical methods used
by Maple, Mathematica etc. For instance : the graph of x^2+y^2=x^3+y^3
GrafEq displays the curve *plus* the singularity at (0,0). If you examine
some of the Gallery graphs - eg 'disks' - there's no way they can be plotted
without interval arithmetic ..."
