ZLARGV(3F) ZLARGV(3F)
ZLARGV  generate a vector of complex plane rotations with real cosines,
determined by elements of the complex vectors x and y
SUBROUTINE ZLARGV( N, X, INCX, Y, INCY, C, INCC )
INTEGER INCC, INCX, INCY, N
DOUBLE PRECISION C( * )
COMPLEX*16 X( * ), Y( * )
ZLARGV generates a vector of complex plane rotations with real cosines,
determined by elements of the complex vectors x and y. For i = 1,2,...,n
( c(i) s(i) ) ( x(i) ) = ( a(i) )
( conjg(s(i)) c(i) ) ( y(i) ) = ( 0 )
N (input) INTEGER
The number of plane rotations to be generated.
X (input/output) COMPLEX*16 array, dimension (1+(N1)*INCX)
On entry, the vector x. On exit, x(i) is overwritten by a(i),
for i = 1,...,n.
INCX (input) INTEGER
The increment between elements of X. INCX > 0.
Y (input/output) COMPLEX*16 array, dimension (1+(N1)*INCY)
On entry, the vector y. On exit, the sines of the plane
rotations.
INCY (input) INTEGER
The increment between elements of Y. INCY > 0.
C (output) DOUBLE PRECISION array, dimension (1+(N1)*INCC)
The cosines of the plane rotations.
INCC (input) INTEGER
The increment between elements of C. INCC > 0.
