#includeIn this example, we create two Vector3f objects and compute their dot product using the 'dot()' function provided by Eigen. The result is stored in a float variable. Package/Library: Eigen.Eigen::Vector3f v1(1.0f, 2.0f, 3.0f); Eigen::Vector3f v2(3.0f, 2.0f, 1.0f); float dotProduct = v1.dot(v2);
