desc.profiles.SplineProfile
- class desc.profiles.SplineProfile(values=None, knots=None, method='cubic2', name='')Source
Profile represented by a piecewise cubic spline.
- Parameters:
params (array-like) – Values of the function at knot locations.
knots (int or ndarray) – x locations to use for spline. If an integer, uses that many points linearly spaced between 0,1
method (str) – method of interpolation - ‘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) – name of the profile
