int sds_xformss (const sds_name setname, sds_matrix transform);
Change this set according to this matrix.
This function changes the positional information for a selection set using the transformation matrix. The sds_xformss function can be used to scale, rotate, or move the selection, as long as the relative proportions of the set are maintained (aspect ratio). This function will not accept a matrix that attempts to change the x-, y-, and z-axes by different values.
The argument setname is the name of the selection set to be transformed.
The argument transform is the transformation matrix to be applied to setname. The matrix may scale the selection set, as long as the scaling factors for each axis are the same.
This function returns RTNORM or an error code in system variable ERRNO.
