- 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 )

- 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 overwritten 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.
