Cubic L-Spline Interpolation at a Biinfinite Knot Sequence
作者姓名:黄达人  王建忠
摘    要:Let further be a strictly increasing sequence with t_(±∞)=limt, We denote Z be the set of all integers, R be the set of all real numbers. Let Problem A For an arbitarily given y=(y_o)∈Y,what conditions should satisfy for existing an unique s(x)∈S_p (Δ)∩L_(t-∞,t+∞)~∞ such that s(t_v)=y,v∈Z? Firstly we assume that β>a>0, hence e~(ax), e~(-ax), e~(βx), e~(-βx) form a base of π(P).
