Description

Use it to draw a function described by a "equation" [z=F(x)] (Z-X plane) The example done here generate a parabol. Has no dialog. Needs to be defined:

F = variable used in the function,
X = initial value of x,
Nb = Number of step,
Z = function express with x
ZZ = function express with xx
