传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。该代码实现了以下功能： 1) 借助MATLAB画出了滤波器的误差性能曲面和误差性能曲面的等值曲线； 2） 给出了最陡下降法以及LMS算法的计算公式； 3） 用MATLAB产生了方差为0.05, 均值为0白噪音S(n)，并画出某次采样得到的波形； 4） 根据 2）中的公式，并利用 3）中产生的S(n)，在 1）中的误差性能曲面的等值曲线上叠加画出了采用最陡下降法以及LMS法时H(n)的在叠代过程中的轨迹曲线； 5）用MATLAB计算并画出了LMS法时误差随时间n的变化曲线（对应S(n)的某一次的一次实现）和e(n)波形； 6）在 1）中的误差性能曲面的等值曲线上，叠加画出采用LMS法得到的100次实验中的H(n)的平均值的轨迹曲线； 7）最终对结果进行了分析，具体见压缩包的word文档。 (Wideband signal in the conventional sinusoidal interference suppression method is the use notch filter (notch filter), this requires precise knowledge of the frequency of a sinusoidal interference .

现今社会网络越来越普及，网购已成为一种常见的消费方式，随之物流行业也渐渐兴盛，每个送货员需要以最快的速度及时将货物送达，而且他们往往一人送多个地方，请设计方案使其耗时最少。 这是数学建模是非常有意思的一个题，本程序用哈密尔顿算法计算(Today more and more popular social networks, online shopping has become a common way of consumption, with the attendant logistics industry has gradually flourished, each delivery person needs to be the fastest speed in time of goods delivery, and they sent the more often a a place, please design it for at least time-consuming. This is the mathematical modeling is a very interesting question, the program algorithm with the Hamilton)
