说明：  在MATLAB环境中，利用简单的加法和乘法实现基2时间抽取的FFT变换，并且能够计算出峰值点的最大值,数据点数为2的整数次幂。学习程序有利于对FFT变换的理解，以及在单片机环境或者是DSP环境中编写FFT变换C语言程序。(In the MATLAB environment, using simple addition and multiplication of time taken to achieve the base 2 FFT transform, and can calculate the maximum peak point. Learning process is conducive to the understanding of the FFT transform, and the DSP in the microcontroller environment, the environment or the preparation of FFT, C language program.)

说明：  该源代码是Leo Grady，基于随机游走算法来实现的图片切割(The source code is Leo Grady, based on random walk algorithm to realize the image cut)
