Function/Subroutine Documentation

subroutine clartv (integerN, complex, dimension( * )X, integerINCX, complex, dimension( * )Y, integerINCY, real, dimension( * )C, complex, dimension( * )S, integerINCC)

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

 N is INTEGER

 The number of plane rotations to be applied.

X

 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

 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

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

 The cosines of the plane rotations.

S

 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.
