Gaurav, I should mention that the solution you obtain for the five coefficients may not actually represent an ellipse but rather a hyperbola or a parabola. If that is the case and there is no other column of S which has a zero singular value, then presumably there exists no ellipse which would run through those four given points. What you actually have here is the solution to a general fourpoint conic which is aligned with the coordinate axes in which the conic can be any one of these three types (or in some cases a degenerate conic.)
