WebJan 19, 2024 · Solution. We know that ˆj × ˆk = ˆi. Therefore, ˆi × (ˆj × ˆk) = ˆi × ˆi = ⇀ 0. Exercise 12.4.3. Find (ˆi × ˆj) × (ˆk × ˆi). Hint. Answer. As we have seen, the dot product is often called the scalar product because it results in a scalar. The cross product results in a vector, so it is sometimes called the vector product. WebAug 23, 2024 · The result, cp, is now multiplied with the matrix Y and all products are summed up: res <- sum (cp * Y, na.rm=T) Now I'm looking for a fast and thus efficient way to perform this calculation in R for all combinations of column vectors of the matrix X.
