给出了迭代函数系统生成Julia集的代码-In this paper, a iterative function system redraw Julia program source code

简单迭代傅里叶变换算法的代码，主要用了快速傅里叶变换函数 (IFTA)-Iterative Fourier Transform Algothrim (IFTA)

运用快速傅里叶转换法fft2和逆转换ifft2反复迭代进行对二维平面函数的处理程序。-Fft2 by applying the method of fast Fourier transformation and reverse change ifft2 repeated iteration of two-dimensional plane function handler.
