For example, to create the average of a set of variables, we can use the following:Given a vector x ∈ (ℝ+)^n and an integer s ∈ ℕ. Find the smallest integer m such that there exists a vector t ∈ (ℝ+)^m and an integer matrix K ∈ ℕ^ (n ⊗ m) which satisfy the following: t * 1 ^m = x * 1 ^n /s ; the sum over all entries of t is the same as that over all entries of x divided by s. 1 ^n * K = 1 ^m * s ; each ...In Euclidean space, a ball is the volume bounded by a sphere. In mathematics, a ball is the solid figure bounded by a sphere; it is also called a solid sphere. It may be a closed ball (including the boundary points that constitute the sphere) or an open ball (excluding them).. These concepts are defined not only in three-dimensional Euclidean space but also for …
