    The Generate the Elements for a Givens Plane Rotation routine
    constructs a Givens plane rotation that eliminates the second
    element of a two-element vector.

    Format

      BLAS1$VSROTG  a ,b ,c ,s

      BLAS1$VDROTG  a ,b ,c ,s

      BLAS1$VGROTG  a ,b ,c ,s

      BLAS1$VCROTG  a ,b ,c ,s

      BLAS1$VZROTG  a ,b ,c ,s

      BLAS1$VWROTG  a ,b ,c ,s

      Use BLAS1$VSROTG for single-precision real operations.
      Use BLAS1$VDROTG for double-precision real (D-floating)
      operations.
      Use BLAS1$VGROTG for double-precision real (G-floating)
      operations.

      Use BLAS1$VCROTG for single-precision complex operations.
      Use BLAS1$VZROTG for double-precision complex (D-floating)
      operations.
      Use BLAS1$VWROTG for double-precision complex (G-floating)
      operations.
