摘要
以R^n表示n维欧氏空间,Z^n表示其中分量皆为整数的点集.对α=(α_1,…,α_n)∈Z^n,称为α的长度.Z_+~n表示Z^n中各分量皆为非负整数的点集.若α∈Z_+~n。
Let {λ_α;α∈Z^2} be a class of functionals such that λ_αM_(r,s,i)(·-β)=δ_(αβ)=1 α=β0 otherwise. where M_(r、s、i) is a bivariate box spline in the three-direction mesh. Howdo we determine λ'_αs using differential operators? We give a simple and completeanswer to this question.
