lacrt(3) Library Functions Manual lacrt(3) NAME lacrt - lacrt: apply plane rotation (unused?) SYNOPSIS Functions subroutine clacrt (n, cx, incx, cy, incy, c, s) CLACRT performs a linear transformation of a pair of complex vectors. subroutine zlacrt (n, cx, incx, cy, incy, c, s) ZLACRT performs a linear transformation of a pair of complex vectors. Detailed Description Function Documentation subroutine clacrt (integer n, complex, dimension( * ) cx, integer incx, complex, dimension( * ) cy, integer incy, complex c, complex s) CLACRT performs a linear transformation of a pair of complex vectors. Purpose: !> !> CLACRT 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. !> CX !> CX is COMPLEX 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 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 !> S !> S is COMPLEX !> C and S define the matrix !> [ C S ]. !> [ -S C ] !> Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
