3.10.1 2D implicit curve
-
plotimplicit(f(x,y),x,y) draws the graphic representation of the
curve defined by the implicit equation f(x,y)=0 when x (resp y)
is in WX-, WX+ (resp in WY-, WY+) defined by cfg,
- plotimplicit(f(x,y),x=0..1,y=-1..1) draws the graphic
representation of the curve defined by the implicit equation f(x,y)=0
when 0≤ x ≤ 1 and −1≤ y ≤ 1
It is possible to add two arguments to specify the discretisation
steps for x
and y with xstep=... and ystep=....
