desc.profiles.SplineProfile

class desc.profiles.SplineProfile(values=None, knots=None, method='cubic2', name='')Source 

Radial profile represented by a piecewise cubic spline.

Parameters:

values (array-like) – 1-D array containing values of the dependent variable.
knots (array-like) – 1-D array containing values of the independent variable. Must be real, finite, and in strictly increasing order in [0, 1]. If None, assumes values is given on knots uniformly spaced in [0, 1].
method (str) – Method of interpolation. Default is cubic2. - ‘nearest’: nearest neighbor interpolation - ‘linear’: linear interpolation - ‘cubic’: C1 cubic splines (aka local splines) - ‘cubic2’: C2 cubic splines (aka natural splines) - ‘catmull-rom’: C1 cubic centripetal “tension” splines
name (str) – Optional name of the profile.
