INVERTIBILITY OF MATRICES OBTAINED DURING SOLVING FREDHOLM EQUATIONS BY WAVELET-GALERKIN METHOD

Considering the antenna of a difficult configuration, we have to work with dense matrixes of big dimension, which are the result by the solution of the systems of the linear algebraic equations that leads to the large expense of time and memory. Applying the Wavelet-Galerkin method, the elements of the matrixes, which are turning out by the sampling the Fredholm equations turn out pseudo-rarefied. It is convenient for as for storage of these elements, and for actions with them for finding of the decision of these systems.
