NAME
zdrot.f -
SYNOPSIS
Functions/Subroutines subroutine zdrot (N, CX, INCX, CY, INCY, C, S) ZDROT Function/Subroutine Documentation subroutine zdrot (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, double precisionC, double precisionS) ZDROT Purpose: Applies a plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex. jack dongarra, linpack, 3/11/78. Parameters: N N is INTEGER On entry, N specifies the order of the vectors cx and cy. N must be at least zero. CX CX is COMPLEX*16 array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). Before entry, the incremented array CX must contain the n element vector cx. On exit, CX is overwritten by the updated vector cx. INCX INCX is INTEGER On entry, INCX specifies the increment for the elements of CX. INCX must not be zero. CY CY is COMPLEX*16 array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). Before entry, the incremented array CY must contain the n element vector cy. On exit, CY is overwritten by the updated vector cy. INCY INCY is INTEGER On entry, INCY specifies the increment for the elements of CY. INCY must not be zero. C C is DOUBLE PRECISION On entry, C specifies the cosine, cos. S S is DOUBLE PRECISION On entry, S specifies the sine, sin. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
