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.
N (input) INTEGER
The number of elements in the vectors CX and CY.
CX (input/output) COMPLEX array, dimension (N)
On input, the vector X. On output, CX is overwritten with C*X + S*Y.
INCX (input) INTEGER
The increment between successive values of CY. INCX <> 0.
CY (input/output) COMPLEX array, dimension (N)
On input, the vector Y. On output, CY is overwritten with -CONJG(S)*X + C*Y.
INCY (input) INTEGER
The increment between successive values of CY. INCX <> 0.
C (input) REAL
S (input) COMPLEX C and S define a rotation [ C S ] [ -conjg(S) C ] where C*C + S*CONJG(S) = 1.0.
