  Throughout this article the major idea and conclusion is about comparing this
method with some very famous methods like fourier series and wavelet, to show
that the power of this approximation method is as much as to predicate many
natural and finance methods, something which we can not say the same for
wavelets and Fourier series, since this method consider the function itself to
make the base functions, and it is more natural rather than wavelets method and
fourier series, which they consider some prior functions as basis.
