grogupy._core.RotM

grogupy._core.RotM(theta: float, u: ndarray[Any, dtype[_ScalarType_co]], eps: float = 1e-10) → ndarray[Any, dtype[_ScalarType_co]][source]

Definition of rotation matrix with angle theta around direction u.

Parameters

theta: float
The angle of rotation

u: NDArray
The rotation axis

eps: float, optional
Cutoff for small elements in the resulting matrix. Defaults to 1e-10

Returns

NDArray
The rotation matrix
