+/*  ======= */
+
+/*  CLARTG generates a plane rotation so that */
+
+/*     [  CS  SN  ]     [ F ]     [ R ] */
+/*     [  __      ]  .  [   ]  =  [   ]   where CS**2 + |SN|**2 = 1. */
+/*     [ -SN  CS  ]     [ G ]     [ 0 ] */
+
+/*  This is a faster version of the BLAS1 routine CROTG, 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 */
+/*          The first component of vector to be rotated. */
+
+/*  G       (input) COMPLEX */
+/*          The second component of vector to be rotated. */
+
+/*  CS      (output) REAL */
+/*          The cosine of the rotation. */

+/*  SN      (output) COMPLEX */
+/*          The sine of the rotation. */
