- BPoly.extend(c, x, right=True)¶
Add additional breakpoints and coefficients to the polynomial.
c : ndarray, size (k, m, ...)
Additional coefficients for polynomials in intervals self.x[-1] <= x < x_right, x_right <= x < x_right, ..., x_right[m-2] <= x < x_right[m-1]
x : ndarray, size (m,)
Additional breakpoints. Must be sorted and either to the right or to the left of the current breakpoints.
right : bool, optional
Whether the new intervals are to the right or to the left of the current intervals.
