摘要
对周期型多重二次样条函数空间,给出了具有点消失矩性质的紧支集半正交小波基及对偶小波基,得到了相应的快速正交投影算法,最后给出了奇性检测性质.
In this paper, a multi-knots periodic spline space with three order is studied, and multi-knots semi-orthogonal spline bases of compactly supported wavelets with point vanishing moments properties can be constucted, and its dual bases also can be obtained. Then the fast scheme of function P mf is given. Finally, the property of sigularity detecting is obtained.
