CSPICE_VUPACK unpacks three scalar double precisions components
from a row form 3-vector.
For important details concerning this module's function, please refer to
the CSPICE routine vupack_c.
vec an arbitrary double precision 3-vector with components x, y, z:
vec = [ x, y, z ]
cspice_vupack, vec_in, x, y, x
z the double precision scalar components of 'vec'.
The action of cspice_vupack reverses the affect of cspice_vpack.
The native IDL code to perform this operation:
x = vec
y = vec
z = vec
