VMS Help RTL Routines, MTH$, BLAS1$VxROT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Apply a Givens Plane Rotation routine applies a Givens plane
    rotation to a pair of n-element vectors x and y.

    Format

      BLAS1$VSROT  n ,x ,incx ,y ,incy ,c ,s

      BLAS1$VDROT  n ,x ,incx ,y ,incy ,c ,s

      BLAS1$VGROT  n ,x ,incx ,y ,incy ,c ,s

      BLAS1$VCSROT  n ,x ,incx ,y ,incy ,c ,s

      BLAS1$VZDROT  n ,x ,incx ,y ,incy ,c ,s

      BLAS1$VWGROT  n ,x ,incx ,y ,incy ,c ,s

      Use BLAS1$VSROT for single-precision real operations.
      Use BLAS1$VDROT for double-precision real (D-floating)
      operations.
      Use BLAS1$VGROT for double-precision real (G-floating)
      operations.

      Use BLAS1$VCSROT for single-precision complex operations.
      Use BLAS1$VZDROT for double-precision complex (D-floating)
      operations.
      Use BLAS1$VWGROT for double-precision complex (G-floating)
      operations.
      BLAS1$VCSROT, BLAS1$VZDROT, and BLAS1$VWGROT are real rotations
      applied to a complex vector.
