Dear list,

Is it possiblet to make implicit plots (i.e. ploting the curves described by equations) in MetaFun? I cannot find anything about them in the MetaFun manual.

For example, in Mathematica I can write something like

ContourPlot[2 x^5 + x y + y^5 == 0, {x, 0, 2}, {y, -2, 1/2}]

you need some " Groebner basis computation " kernel to do this kind of computations. Have a look at https://www-fourier.ujf-grenoble.fr/~parisse/giac.html -- luigi
