       void srotm(int n, float  *x,  int  incx,  float  *y,  int  incy,  float
                 *param);

                 *param);



PURPOSE
       srotm Apply a Given's rotation constructed by SROTMG.


ARGUMENTS
       N (input)
                 On entry, N specifies the number of elements in  the  vector.
                 N must be at least one for the subroutine to have any visible
                 effect.  Unchanged on exit.


       X (input/output)
                 ( 1 + ( n - 1 )*abs( INCX ) ).   On  entry,  the  incremented
                 array  X must contain the vector x. On exit, X is overwritten
                 by the updated vector x.


       INCX (input)
                 On entry, INCX specifies the increment for the elements of X.
                 INCX must not be zero.  Unchanged on exit.


       Y (input/output)
                 (  1  +  (  n - 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 (input)
                 On entry, INCY specifies the increment for the elements of Y.
                 INCY must not be zero.  Unchanged on exit.


       PARAM (input)
                 On  entry,  the  rotation  values  constructed   by   SROTMG.
                 Unchanged on exit.
