Function/Subroutine Documentation

subroutine clartv (integer n, complex, dimension( * ) x, integer incx, complex, dimension( * ) y, integer incy, real, dimension( * ) c, complex, dimension( * ) s, integer incc)

CLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.

Purpose:



 CLARTV applies a vector of complex plane rotations with real cosines


 to elements of the complex vectors x and y. For i = 1,2,...,n


    ( x(i) ) := (        c(i)   s(i) ) ( x(i) )


    ( y(i) )    ( -conjg(s(i))  c(i) ) ( y(i) )

Parameters



          N is INTEGER


          The number of plane rotations to be applied.



          X is COMPLEX array, dimension (1+(N-1)*INCX)


          The vector x.

INCX



          INCX is INTEGER


          The increment between elements of X. INCX > 0.



          Y is COMPLEX array, dimension (1+(N-1)*INCY)


          The vector y.

INCY



          INCY is INTEGER


          The increment between elements of Y. INCY > 0.



          C is REAL array, dimension (1+(N-1)*INCC)


          The cosines of the plane rotations.



          S is COMPLEX array, dimension (1+(N-1)*INCC)


          The sines of the plane rotations.

INCC



          INCC is INTEGER


          The increment between elements of C and S. INCC > 0.
