zswap() void zswap ( int  n, doublecomplex  zx[], int  incx, doublecomplex  zy[], int  incy  ) y <-> x (complex vector) (BLAS 1) Purpose This routine interchanges two complex vectors. Parameters [in] n Number of elements in vectors x and y. (If n <= 0, returns without computation) [in,out] zx[] Array zx[lzx] (lzx >= 1 + (n - 1)*abs(incx)) [in] Input vector x [out] Output vector (= input vector y) [in] incx Storage spacing between elements of x. [in,out] zy[] Array zy[lzy] (lzy >= 1 + (n - 1)*abs(incy)) [in] Input vector y [out] Output vector (= input vector x) [in] incy Storage spacing between elements of y. Reference BLAS
