crot.f(3) LAPACK crot.f(3)NAME

crot.f-SYNOPSIS

Functions/Subroutines subroutine crot (N, CX, INCX, CY, INCY, C, S) CROT applies a plane rotation with real cosine and complex sine to a pair of complex vectors.Function/Subroutine Documentation subroutine crot (integerN, complex, dimension( * )CX, integerINCX, complex, dimension( * )CY, integerINCY, realC, complexS) CROT applies a plane rotation with real cosine and complex sine to a pair of complex vectors. Purpose: 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. 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 CY. INCX <> 0. CY CY is COMPLEX array, dimension (N) On input, the vector Y. On output, CY is overwritten with -CONJG(S)*X + C*Y. INCY INCY is INTEGER The increment between successive values of CY. INCX <> 0. C C is REAL S S is COMPLEX C and S define a rotation [ C S ] [ -conjg(S) C ] where C*C + S*CONJG(S) = 1.0.
