Purpose:ZLACRT performs the operation ( c s )( x ) ==> ( x ) ( s c )( y ) ( y ) where c and s are complex and the vectors x and y are complex. N

N is INTEGER The number of elements in the vectors CX and CY.CX CX is COMPLEX*16 array, dimension (N) On input, the vector x. On output, CX is overwritten with c*x + s*y.INCX INCX is INTEGER The increment between successive values of CX. INCX <> 0.CY CY is COMPLEX*16 array, dimension (N) On input, the vector y. On output, CY is overwritten with s*x + c*y.INCY INCY is INTEGER The increment between successive values of CY. INCY <> 0.C C is COMPLEX*16S S is COMPLEX*16 C and S define the matrix [ C S ].
