Function rgsl::polynomials::divided_difference_representation::poly_dd_taylor

pub fn poly_dd_taylor(
    c: &mut [f64],
    xp: f64,
    dd: &[f64],
    xa: &[f64],
    w: &mut [f64]
) -> Value

This function converts the divided-difference representation of a polynomial to a Taylor expansion. The divided-difference representation is supplied in the arrays dd and xa of length size. On output the Taylor coefficients of the polynomial expanded about the point xp are stored in the array c also of length size. A workspace of length size must be provided in the array w.
