eval_poly

tayph.eval_poly(x, f)

This evaluates a polynomial using fitting coefficients f that were found via np.polyfit(x,y). Normally you could use numpy.polynomial.polynomial.Polynomlial(fit)(x) for this, but not if fit is a 2D array found by using np.polyfit(x,Y) with Y 2D. To deal with this eval_poly evaluates a sequence of polynomials for a sequence of fits, on x. If you want to rip this out of tayph for your own purposes, all you need to remove is the test functions.

Parameters

xnp.ndarray

A 1D array with x values.

fnp.ndarray

A 1D or 2D array containing polynomial coefficients.
