CSPICE_VNORM returns a scalar double describing the vector norm
of a 3-vector where the vector norm is defined as the magnitude of
For important details concerning this module's function, please refer to
the CSPICE routine vnorm_c.
vec an arbitrary double precision 3-vector.
norm = cspice_vnorm( vec )
norm the double precision scalar norm of 'vec'.
Native IDL code to calculate the same scalar result:
vec_norm = norm( vec )
The IDL norm function accepts an arbitrary size N vector.
