5.3.3. nvector.rotation.n_E_and_wa2R_EL¶
-
n_E_and_wa2R_EL
(n_E, wander_azimuth, R_Ee=None)[source]¶ Returns rotation matrix R_EL from n-vector and wander azimuth angle.
- Parameters
- n_E: 3 x n array
n-vector [no unit] decomposed in E
- wander_azimuth: real scalar or array of length n
Angle [rad] between L’s x-axis and north, positive about L’s z-axis.
- R_Ee3 x 3 array
rotation matrix defining the axes of the coordinate frame E.
- Returns
- R_EL: 3 x 3 x n array
The resulting rotation matrix. [no unit]
Notes
When wander_azimuth=0, we have that N=L. (See Table 2 in Gade (2010) for details)
