swap(3) LAPACK swap(3) NAME swap - swap: x <=> y SYNOPSIS Functions subroutine cswap (n, cx, incx, cy, incy) CSWAP subroutine dswap (n, dx, incx, dy, incy) DSWAP subroutine sswap (n, sx, incx, sy, incy) SSWAP subroutine zswap (n, zx, incx, zy, incy) ZSWAP Detailed Description Function Documentation subroutine cswap (integer n, complex, dimension(*) cx, integer incx, complex, dimension(*) cy, integer incy) CSWAP Purpose: CSWAP interchanges two vectors. Parameters N N is INTEGER number of elements in input vector(s) CX CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) INCX INCX is INTEGER storage spacing between elements of CX CY CY is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) INCY INCY is INTEGER storage spacing between elements of CY Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Further Details: jack dongarra, linpack, 3/11/78. modified 12/3/93, array(1) declarations changed to array(*) Definition at line 80 of file cswap.f. subroutine dswap (integer n, double precision, dimension(*) dx, integer incx, double precision, dimension(*) dy, integer incy) DSWAP Purpose: DSWAP interchanges two vectors. uses unrolled loops for increments equal to 1. Parameters N N is INTEGER number of elements in input vector(s) DX DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) INCX INCX is INTEGER storage spacing between elements of DX DY DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) INCY INCY is INTEGER storage spacing between elements of DY Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
