Teaching Wavelets in XploRe1
نویسندگان
چکیده
Teachware is a set of computer software tools for computeraided interactive teaching of certain knowledge elements. The construction of teachware for statistical knowledge is a rather young eld since it heavily depends on data structures and graphical interaction possibilities. In this paper we present a teachware module for XploRe-a statistical computing environment. We focus on the situation of teaching wavelets, a technique for adaptation of spatial inhomogeneity. 1 The authors and the wavelet tutorial are accessible via WWW Financial support was received by the Deutsche Forschungsgemeinschaft, SFB 373 ("Quan-tiikation und Simulation Okonomischer Prozesse"), Humboldt-Universitt at zu Berlin.

متن کاملNUMERICAL SOLUTION OF LINEAR FREDHOLM AND VOLTERRA INTEGRAL EQUATION OF THE SECOND KIND BY USING LEGENDRE WAVELETS
In this paper, we use the continuous Legendre wavelets on the interval [0,1] constructed by Razzaghi M. and Yousefi S. [6] to solve the linear second kind integral equations. We use quadrature formula for the calculation of the products of any functions, which are required in the approximation for the integral equations. Then we reduced the integral equation to the solution of linear algebraic ...
