   C INTERFACE

       void  csrot(int n, complex *x, int incx, complex *y, int incy, float c,
                 float s);

       void csrot_64(long n, complex *x, long incx,  complex  *y,  long  incy,
                 float c, float s);



PURPOSE
       csrot  Apply a plane rotation, where the cos and sin (c and s) are real
       and the vectors x and y are complex.


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), dimension (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), dimension (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.


       C (input)
                 On entry, the cosine.  Unchanged on exit.


       S (input)
                 On entry, the sin.  Unchanged on exit.
