matrix  pointtransformsrigid(<geometry>geometry, int pnts)
matrix  pointtransformsrigid(<geometry>geometry)
Returns an array of rigid transforms associated with the point indices. This function queries the
v@P and the
3@transform attributes to build matrices. Polar decomposition is performed on
3@transform to make it rigid.
Returns all the point transforms if the point indices argument is omitted.
The array of point indices to query.
