NAME CLARGV - generate a vector of complex plane rotations with real cosines, determined by elements of the complex vectors x and y SYNOPSIS SUBROUTINE CLARGV( N, X, INCX, Y, INCY, C, INCC ) INTEGER INCC, INCX, INCY, N REAL C( * ) COMPLEX X( * ), Y( * ) PURPOSE CLARGV 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 ) ARGUMENTS N (input) INTEGER The number of plane rotations to be generated. X (input/output) COMPLEX array, dimension (1+(N- 1)*INCX) On entry, the vector x. On exit, x(i) is overwrit- ten by a(i), for i = 1,...,n. INCX (input) INTEGER The increment between elements of X. INCX > 0. Y (input/output) COMPLEX array, dimension (1+(N- 1)*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) REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations. INCC (input) INTEGER The increment between elements of C. INCC > 0.
