P. S. Zykov, E. B. Postnikov

AI总结:

摘要:

提出了一种计算汉克尔变换的方法,该方法通过将被积函数表示为光滑函数乘以贝塞尔函数,将其简化为求和。光滑函数被替换为其小波分解,使用一种基函数,使得其与贝塞尔函数的内积可以解析计算。结果表示为一个级数,其中系数强烈依赖于被变换函数的局部行为。通过一个示例展示了该方法的应用,并附有图示。

英文摘要:

A method for computing the Hankel transform is proposed whereby the letter is reduced to a sum by representing the integrand as a smooth function times a Bessel function. The smooth function is replaced by its wavelet decomposition with a basis such that its scalar product with the Bessel function is calculated analytically. The result is represented as a series, with the coefficients strongly depending on the local behavior of the function being transformed. The application of the method is demonstrated by an example illustrated with plots.
