CL_mod_nutationMatrix

Description

• This function is deprecated.

• Computes the nutation matrix and the rotation vectors (standard IERS 1996).

Parameters

K :

[EPS0 ; DPSI ; DEPS ] (3xN)

KP :

[EPS0P ; DPSIP ; DEPSP] (3xN)

KPP :

[EPS0PP; DPSIPP; DEPSPP] (3xN)

flag :

(optional) "n" -> matrix only; "p" -> matrix and rotation vector; "s" -> matrix, rotation vector and its time derivative (default depends on number of outputs)

NUT :

Nutation matrix (3x3xN)

OM :

(optional) Rotation vectors (3xN)

OMP :

(optional) first time derivative of OM (3xN)
