NAME
       csrot - Apply a plane rotation.

SYNOPSIS
       SUBROUTINE CSROT(N, X, INCX, Y, INCY, C, S)

       REAL C, S
       COMPLEX X(*), Y(*)
       INTEGER N, INCX, INCY

       SUBROUTINE CSROT_64(N, X, INCX, Y, INCY, C, S)

       REAL C, S
       COMPLEX X(*), Y(*)
       INTEGER*8 N, INCX, INCY

   F95 INTERFACE
       SUBROUTINE ROT([N], X, [INCX], Y, [INCY], C, S)

       REAL :: C, S
       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER :: N, INCX, INCY

       SUBROUTINE ROT_64([N], X, [INCX], Y, [INCY], C, S)

       REAL :: C, S
       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER(8) :: N, INCX, INCY

   C INTERFACE
       #include <sunperf.h>

       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.
