Approximation of data using cubic bezier curve least square fitting. If you need exact, unless you have only as many points as the curve order you need, getting a true bezier curve is almost guaranteed impossible, unless you want a poly bezier curve, in which case you can just do piecewise curve fitting, and then a catmull rom split is far more useful and converts to, and from, a poly bezier curve mike.
