Draw2d

Function: draw2d (<option>, <graphic_object>, ...) This function is a short cut for draw(gr2d(<options>, ..., <graphic_object>, ...)).

load(draw);
draw2d(implicit(y*x^3+y^3-2*(x+100)*y^2-3*x*y=0,x,-500,500,y,-500,500));

It can be used to plot a unique scene in 2d.

To make use of this function, write first load(draw).

See also draw and gr2d.
