A Gauss quadrature method in which the wavelet is used as a weighting
function is developed for wavelet BEM.
Non-orthogonal spline wavelets that
can change the order of vanishing moments as well as the order of polyno-
mial are considered in BE analysis.
Although the increase in the order of
vanishing moments leads to the increase in the sparseness of matrices, that
also increases the number of intervals in which the wavelet is described by a
The proposed quadrature method does not need to di-
vide the support of wavelets in the calculation of matrix coefficients, while
the Gauss-Legendre formula obliges us to divide the support into several
Consequently the proposed method allows to reduce the com-
putational work for generation of matrices.
