-*  Purpose
-*  =======
-*
-*  ZLARTG generates a plane rotation so that

-*
-*  This is a faster version of the BLAS1 routine ZROTG, except for
-*  the following differences:
-*     F and G are unchanged on return.
-*     If G=0, then CS=1 and SN=0.
-*     If F=0, then CS=0 and SN is chosen so that R is real.
-*
-*  Arguments
-*  =========
-*
-*  F       (input) COMPLEX*16
-*          The first component of vector to be rotated.
-*
-*  G       (input) COMPLEX*16
-*          The second component of vector to be rotated.
-*
-*  CS      (output) DOUBLE PRECISION
-*          The cosine of the rotation.
-*
-*  SN      (output) COMPLEX*16
-*          The sine of the rotation.
-*
-*  R       (output) COMPLEX*16
-*          The nonzero component of the rotated vector.
