bootHyperbola

This function is not intended for direct use. It attempts to generate an approximate fit of a data set to a hyperbola, returning a parameter set for use in intializing the main function <code>conicFit</code> .

Fit data to an ellipse, hyperbola, or parabola. Bootstrapping is available when needed. The conic curve can be rotated through an arbitrary angle and the fit will still succeed. Helper functions are provided to convert generator coefficients from one style to another, generate test data sets, rotate conic section parameters, and so on.
