splinepy.bspline.BSpline.greville_abscissae

BSpline.greville_abscissae(duplicate_tolerance=None)

Returns greville abscissae.

Parameters:

duplicate_tolerance (float) – If negative, duplicates are possible for C^(-1) splines (B-Spline family). Otherwise they are filtered out using adjacent abscissae. Value represents tolerance between two greville abscissae, to be considered as equal

Returns:

greville_abscissae

Return type:

(para_dim) np.ndarray
