n_E2R_EN
(n_E, R_Ee=None)[source][source]¶ Returns the rotation matrix R_EN from n-vector.
Parameters: - n_E: 3 x n array
n-vector [no unit] decomposed in E
- R_Ee : 3 x 3 array
rotation matrix defining the axes of the coordinate frame E.
Returns: - R_EN: 3 x 3 x n array
The resulting rotation matrix [no unit] (direction cosine matrix).
