EllipticCurves :: isOnEllCurve(List,EllipticCurve)

isOnEllCurve(List,EllipticCurve) -- A method to check if a point is on an elliptic curve.

Synopsis

Description

Tells whether the point of projecive coordinates { L#0 : L#1 : L#2 } is on the elliptic curve E

i1 : E=ellCurve(3,8,GF(13))

o1 = Elliptic Curve defined by Y^2 = X^3 + 3 X + (-5)( over(GF 13 .))

o1 : EllipticCurve
i2 : isOnEllCurve({1,5,1},E)

o2 = true
