cherab.imas.math.functions.fourier_bezier.py_bezier_basis_derivative_wrt_t¶

cherab.imas.math.functions.fourier_bezier.py_bezier_basis_derivative_wrt_t(s: float, t: float) → ndarray¶

Calculate the derivative of the bezier basis w.r.t. \(t\) for each node and degree of freedom.

Note

This is the python wrapper for the Cython function bezier_basis_derivative_wrt_t(). If you are using this function in a loop, consider using the Cython function directly.

Parameters:

s : float¶

First parameter in the range [0, 1].

t : float¶

Second parameter in the range [0, 1].

Returns:

(4, 4) ndarray – Derivative of the bezier basis w.r.t. \(t\) for each node and degree of freedom. Axis 0: Node index. Axis 1: Degree of freedom index.
