说明：  K-均值聚类(K-means clustering)是Mac Queen提出的一种非监督实时聚类算法,在最小化误差函数的基础上将数据划分为预定的类数K(We study terrestrial wireless localization systems where multiple synchronized infrastructure devices simultaneously transmit signals whose arrival times are measured at an object of interest.)

假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。 已设计一FIR维纳滤波器，选择Kalman滤波器进行滤波处理，确定最佳传递函数，并用该滤波器处理观测信号，得到其最佳估计。(Assume that a point target moves circularly around the unit circle in the x, y plane, and its movement trajectory shifts due to outside interference. Among them, the interference in the x direction is Gaussian noise with a mean of 0 and a variance of 0.05; the y-direction interference is Gaussian noise with a mean of 0 and a variance of 0.06. An FIR Wiener filter has been designed. The Kalman filter is selected for filtering, the best transfer function is determined, and the filter is used to process the observed signal to obtain the best estimate.)

这些代码用于循环移位操作，方便快捷，使用C++编写，简单易懂。(These codes are used for circular shift operation, which is convenient and quick, and is easy to understand by using C++.)

旅行商问题，两种方法实现，分别是递归回溯和用栈来代替递归的功能的程序-Traveling salesman problem, two methods to achieve, namely, retrospective and the use of recursive stack instead of recursive function procedures

说明：  多分类支持向量机，从原开发者的官方网站下载而来，里面有详细的使用说明，多分类的参数选择同样也有说明文件进行说明(Multi-class support vector machine, downloaded from the official website of the original developer, there are detailed instructions for use, and the parameter selection of multi-class also has a description file to explain)

指出了非线性动态信号参数辨识的重要性；分析了目前采用的方法的不足；对非正交复Morlet小波满足Mercy条件和再生性的命题作了证明；用复Morlet小波构建出一种核函数，与主分量分析方法相结合，对非线性动态信号进行参数辨识和预测；仿真结果验证了该方法的正确性和有效性，表明该方法具有较好的理论价值和实用价值。 (Pointed out the nonlinear dynamic signals the importance of parameter identification analysis of the current shortcomings of the method used for non-orthogonal complex Morlet wavelet Mercy meet the conditions and regeneration of the proposition was made to prove using complex Morlet wavelet to build a nuclear function, with the principal component analysis approach combining nonlinear dynamic parameter identification and signal prediction simulation results verify the correctness and effectiveness, show that the method has a better theoretical value and practical value.)
