Function/Subroutine Documentation
subroutine zlacrt (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, complex*16C, complex*16S)
ZLACRT performs a linear transformation of a pair of complex vectors.
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.
Parameters:

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