chemcoord.xyz_functions.apply_grad_zmat_tensor¶

chemcoord.xyz_functions.apply_grad_zmat_tensor(grad_C, construction_table, cart_dist)[source]¶

Apply the gradient for transformation to Zmatrix space onto cart_dist.

Parameters:	grad_C (`numpy.ndarray`) – A `(3, n, n, 3)` array. The mathematical details of the index layout is explained in `get_grad_zmat()`. construction_table (pandas.DataFrame) – Explained in `get_construction_table()`. cart_dist (`Cartesian`) – Distortions in cartesian space.
Returns:	Distortions in Zmatrix space.
Return type:	`Zmat`
