0 |
{{1, 2, 3} dot {2, 4, 6}} |

Comments
The dot operator computes a scalar which is the dot product of vec_expr_1 and vec_expr_2. Both vec_expr_1 and vec_expr_2 must be vectors with the same number of elements. The result is the sum of the products of the corresponding elements of vec_expr_1 and vec_expr_2. If the result is zero, vec_expr_1 and vec_expr_2 are orthogonal.
