(n_E, R_Ee=None)[source][source]¶ Returns the rotation matrix R_EN from n-vector.
Parameters: n_E: 3 x 1 array
n-vector [no unit] decomposed in E
R_Ee : 2d array
rotation matrix defining the axes of the coordinate frame E.
Returns: R_EN: 3 x 3 array
The resulting rotation matrix [no unit] (direction cosine matrix).
