(constant)

   the call:

      [normal, point] = <b>cspice_pl2nvp</b>( plane )

   returns:

      normal   [3,1] = size(normal); double = class(normal)

      point    [3,1] = size(point); double = class(point)

               are, respectively, a unit normal vector and point
               that define the geometric plane represented by
               plane.  Let the symbol &lt; a, b &gt; indicate the inner
               product of vectors a and b; then the geometric
               plane is the set of ve
