摘要：
In this paper we present an approach to construct second generation interpolating wavelets to compress the class of integral operators of the form integral K(x, y)dy over an unstructured grid in 3-D. This approach results in a scheme that generally requires O(N) storage at O(N) cost. Moreover, analytical estimates of the stiffness matrix coefficients are derived. Numerical results are presented for a second kind formulation of Laplace equation.
