设Bn:={b 0,b1,.,bn}(n= 0,1,..,N;N∈N)为线性无关函数集.本文给出了一个简单的构造方法,对偶函数Dn:={d 0(n),d1(n),.,dn(n)}(0≤n≤N)满足以下条件:spanDn= spanBij <bi,dj(n)>=δij(0≤i,j≤n≤N),其中δii=1,δij=0,i ∈ j,<bi,dj>是给定的内积.该算法允许我们在O(N3)时间内构造所有对偶函数D 0,D1,.,DN的集合,其中N是自然数.四个说明性的例子给出所获得的结果的可能的应用。
Let Bn:={b0,b1,…,bn}(n=0,1,…,N;N∈N) be the sets of linearly independent functions. We give a simple method of construction, the dual functions Dn:={d0(n),d1(n),…,dn(n)}(0≤n≤N) satisfying the following conditions: spanDn=spanBnand <bi,dj(n)>=δij(0≤i,j≤n≤N), where δii=1, δij=0 for i≠j, and <⋅,⋅> is a given inner product. The proposed algorithm allows us to construct all the sets of the dual functions D0,D1,…,DNin the time O(N3), where N is a natural number. Four illustrative examples presenting the possible applications of obtained results are given.
