Function/Subroutine Documentation

subroutine clacrt (integer n, complex, dimension( * ) cx, integer incx, complex, dimension( * ) cy, integer incy, complex c, complex s)

CLACRT performs a linear transformation of a pair of complex vectors.  

Purpose:

 CLACRT performs the operation

    (  c  s )( x )  ==> ( x )
    ( -s  c )( y )      ( y )

 where c and s are complex and the vectors x and y are complex.
Parameters

N

          N is INTEGER
          The number of elements in the vectors CX and CY.

CX

          CX is COMPLEX array, dimension (N)
          On input, the vector x.
          On output, CX is overwritten with c*x + s*y.

INCX

          INCX is INTEGER
          The increment between successive values of CX.  INCX <> 0.

CY

          CY is COMPLEX array, dimension (N)
          On input, the vector y.
          On output, CY is overwritten with -s*x + c*y.

INCY

          INCY is INTEGER
          The increment between successive values of CY.  INCY <> 0.

C

          C is COMPLEX

S

          S is COMPLEX
          C and S define the matrix
             [  C   S  ].
             [ -S   C  ]
