desc.geometry.FourierXYZCurve.compute_curvature

FourierXYZCurve.compute_curvature(X_n=None, Y_n=None, Z_n=None, grid=None)[source]

Compute curvature using specified coefficients.

Parameters:

  • X_n (array-like) – fourier coefficients for X, Y, Z. If not given, defaults to values given by X_n, Y_n, Z_n attributes

  • Y_n (array-like) – fourier coefficients for X, Y, Z. If not given, defaults to values given by X_n, Y_n, Z_n attributes

  • Z_n (array-like) – fourier coefficients for X, Y, Z. If not given, defaults to values given by X_n, Y_n, Z_n attributes

  • grid (Grid or array-like) – dependent coordinates to compute at. Defaults to self.grid If an integer, assumes that many linearly spaced points in (0,2pi)

Returns:

kappa (ndarray, shape(k,)) – curvature of the curve at specified grid locations in phi
