利用蝶形算法，实现快速傅立叶变换及其逆变换(The use of butterfly algorithm, fast Fourier transform and its inverse transform)

在重构相空间的基础上计算吸引子的分形维时,合适的嵌入维m和时间滞后τ的选取至关重要.在虚假邻域概念基础上,本文给出了确定m和τ的方法.较之以前的方法,此方法更准确、简单、容易理解、易实施,对较小样本数据集也可靠.最后的应用实例验证了理论的正确性.(In the reconstructed phase space based on the calculation of the fractal dimension of attractor, the appropriate embedding dimension m and time lag τ selection is essential. In a mock neighborhood based on the concept, this paper presents the method to determine m and τ. Compared with the previous methods, this method is more accurate, simple, easy to understand, easy to implement on a smaller set of sample data is also reliable. The last application example to verify the theoretical correctness.)

遗传算法的一个例子。用来实现用遗传算法计算一个简单函数的最小值。(An example of the genetic algorithm)

老师要求的实验作业，matlab上实现了dtmf。添加了gui界面(dtmf gui)

基于MIMO的信道容量sum rate的计算，基于MMSE、ZF、多项式、BF四种准则方法的计算过程，计算结果正确，内附说明文档(Channel capacity sum rate is calculated based on MIMO-based calculation MMSE, ZF, polynomial, BF four criteria method, calculation results correctly, enclosing documentation)

Gold序列是基于m序列优选对产生的，是由两个长度相同、速率相同、但码字不同的m序列优选对模2加后得到的，一对长度为N的m序列优选对可以产生N＋2条Gold码。(Gold sequence is based on the optimization of m sequences generated by both the length of the same, the same rate, but different m codeword sequence optimization of mode 2 increases obtained, a pair of length N of the m sequence optimization can generate N 2 Article Gold code.)

汇集了大量的小波分析例子，详细的介绍小波分析的应用范围(Collection of a large number of examples of wavelet analysis, detail the scope of application of wavelet analysis)

自己编写的一种快速均值漂移聚类算法。数据需要自己下载，里面有main函数,改成自己的数据就可以运行。主要思路是先用近邻规则粗分类，在运行均值漂移。(fast mean shif clustering algorithm.)
