CROT applies a plane rotation with real cosine and complex sine to a pair of complex vectors.
Download CROT + dependencies [TGZ] [ZIP] [TXT]CROT applies a plane rotation, where the cos (C) is real and the sin (S) is complex, and the vectors CX and CY are complex.
[in]  N  N is INTEGER The number of elements in the vectors CX and CY. 
[in,out]  CX  CX is COMPLEX array, dimension (N) On input, the vector X. On output, CX is overwritten with C*X + S*Y. 
[in]  INCX  INCX is INTEGER The increment between successive values of CY. INCX <> 0. 
[in,out]  CY  CY is COMPLEX array, dimension (N) On input, the vector Y. On output, CY is overwritten with CONJG(S)*X + C*Y. 
[in]  INCY  INCY is INTEGER The increment between successive values of CY. INCX <> 0. 
[in]  C  C is REAL 
[in]  S  S is COMPLEX C and S define a rotation [ C S ] [ conjg(S) C ] where C*C + S*CONJG(S) = 1.0.
