摘要:
本文提出了一种基于超函数理论的傅里叶变换数值方法。在所提出的方法中,我们计算出称为定义函数的解析函数,这些函数给出了所需的傅里叶变换作为超函数,然后通过将定义函数解析延拓到实轴上获得傅里叶变换。数值实验显示,该方法在效率上优于先前的方法。
英文摘要:
In this paper, we propose a numerical method of Fourier transform based on hyperfunction theory. In the proposed method, we compute analytic functions called the defining functions, which give the desired Fourier transform as a hyperfunction, and then obtain the Fourier transform by the analytic continuation of the defining functions onto the real axis. Numerical examples show the efficiency of the proposed method compared to the previous methods.
