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)
