zdotu() doublecomplex zdotu ( int  n, doublecomplex  zx[], int  incx, doublecomplex  zy[], int  incy  ) xT * y (complex vector) (BLAS 1) Purpose This routine forms the dot product of two complex vectors (x^T*y). Returns Dot product of vectors x and y (x^T*y). Parameters [in] n Number of elements in vectors x and y. (If n <= 0, returns 0) [in] zx[] Array zx[lzx] (lzx >= 1 + (n - 1)*abs(incx)) Input vector x. [in] incx Storage spacing between elements of x. [in] zy[] Array zy[lzy] (lzy >= 1 + (n - 1)*abs(incy)) Input vector y. [in] incy Storage spacing between elements of y. Reference BLAS
