colour.lagrange_coefficients# colour.lagrange_coefficients(r: float, n: int = 4) → NDArrayFloat[source]# Compute the Lagrange Coefficients at given point \(r\) for degree \(n\). Parameters: r (float) – Point to get the Lagrange Coefficients at. n (int) – Degree of the Lagrange Coefficients being calculated. Return type: numpy.ndarray References [Fai85], [Wikipedia03a] Examples >>> lagrange_coefficients(0.1) array([ 0.8265, 0.2755, -0.1305, 0.0285])
