EllipseFromEquation: Ellipse from its implicit equation

Description

Return an ellipse from the coefficients of its implicit equation.

Usage

EllipseFromEquation(A, B, C, D, E, F)

Arguments

A, B, C, D, E, F

the coefficients of the equation

Value

An Ellipse object.

Details

The implicit equation of the ellipse is Ax<U+00B2> + Bxy + Cy<U+00B2> + Dx + Ey + F = 0. This function returns the ellipse given A, B, C, D, E and F.

Examples

# NOT RUN {
ell <- Ellipse$new(c(2,3), 5, 4, 30)
cf <- ell$equation()
ell2 <- EllipseFromEquation(cf[1], cf[2], cf[3], cf[4], cf[5], cf[6])
ell$isEqual(ell2)
# }
