目标做转弯运动，利用卡尔曼滤波器对其进行跟踪滤波(Goal to make the turning movement, using the Kalman filter tracking filter)

对复杂网络进行判定是否是连通图，输入参数是网络的邻接矩阵，如果是连通图，输出是1，如果不是，输出0.(directed or undirected graph)

扩频信号产生，频谱显示............................(Spread spectrum signal generator, spectrum display)

数字信号处理的MATLAB实现，书中附带的程序代码(Digital signal processing implementation of MATLAB, the book attached to program code)

This example shows the use of the FFT function for spectral analysis. A common use of FFT s is to find the frequency components of a signal buried in a noisy time domain signal.

对MATLAB环境下的迭代算法实现进行了讲述，对熟悉Matlab软件的人有帮助(The MATLAB environment iterative algorithm has been talk, for people who are familiar with Matlab software to help)

4) 创建一个名为Complex的类，进行复数的算术运算。复数的形式为： realpart+imaginarypart*i 用浮点变量表示类的private数据。提供构造函数，能够对所声明的该类对象进行初始化。在不提供初始化值的情况下，该构造函数应包含默认值。针对以下功能，分别提供一个public成员函数。 （1）两个复数相加； （2）两个复数相减 （3）用（a, b）的形式打印复数，其中a为实部，b为虚部。 (4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)
