Constructing a quasi-Legendre basis based on the C-Bézier basis被引量：5
《Progress in Natural Science:Materials International》2005年第6期559-563,共5页HUANGYu WANGGuozhao 
SupportedbytheNationalNaturalScienceFoundationofChina(GrantNo.60473130)
In the space Γ_n = span { sint, cost, 1, t, t^2, ···, t^(n-2)}, aC-Bezier basis is constructed by an integral approach. Howev- er, the C-Bezier basis is notorthogonal. For some applications, we construct an orthog...
