NAME
     srotm - Apply a Gentleman's modified Given's  rotation  con-
     structed by SROTMG.

SYNOPSIS
     SUBROUTINE SROTM (N, X, INCY, Y, INCY, PARAM)

     INTEGER INCX, INCY, N

     REAL    PARAM(5), X( * ), Y( * )



     #include <sunperf.h>

     void srotm(int n, float *dx, int incx, float *dy, int  incy,
               float *sparam) ;

PURPOSE
     SROTM - Apply a Given's rotation constructed by SROTMG.


PARAMETERS
     N         - INTEGER.
               On entry, N specifies the number  of  elements  in
               the  vector.   N must be at least one for the sub-
               routine to have any visible effect.  Unchanged  on
               exit.

     X         - REAL array of DIMENSION at least
               ( 1 + ( n - 1 )*abs( INCX ) ).  Before entry,  the
               incremented  array  X  must  contain the vector x.
               Unchanged on exit.

     INCX      - INTEGER.
               On entry, INCX specifies  the  increment  for  the
               elements  of  X. INCX must not be zero.  Unchanged
               on exit.

     Y         - REAL array of DIMENSION at least
               ( 1 + ( m - 1 )*abs( INCY  )  ).   On  entry,  the
               incremented  array Y must contain the vector y. On
               exit, Y is overwritten by the updated vector y.

     INCY      - INTEGER.
               On entry, INCY specifies  the  increment  for  the
               elements  of  Y. INCY must not be zero.  Unchanged
               on exit.

     PARAM     - REAL
               On  entry,  the  rotation  values  constructed  by
               SROTMG.  Unchanged on exit.
