Transformation of the quadratic conic representation into the matrix representation.
quadraticFormToMatrix(v)
A \((3 \times 3)\) matrix representation of the conic (symmetric matrix).
a \((6 \times 1)\) vector of the parameters \((a, b, c, d, e, f)\) of the quadratic form \(ax^2 + bxy + cy^2 + dxz + eyz + fz^2 = 0\).
v <- c(2,2,-2,-20,20,10) quadraticFormToMatrix(v)
