网上查找的关于决策树的matlab代码，可与参考参考(Tree on the Internet to find the matlab code, with REFERENCES)

数字波束形成，更改指向，更改阵元数量，加噪声(DBF beam forming )

利用CTD测量的压力、温度、电导率数据，获得盐度、声速、密度。(Derive slainity, sound velocity and densinity CTD data.)

说明：  利用反步法实现路径跟踪，包括直线、椭圆，圆轨迹等(Path backtracking with backstepping)

上课时用的课件,是用matlab进行讲解的(class with the courseware is used to explain the Matlab)

说明：  数学建模大赛常用的建模模型，对全国建模大赛很有帮助的啊！(Modeling Mathematical Modeling Contest common model of the national modeling contest helpful ah!)

目标检测与识别中，发生非刚性形变目标之间的点匹配算法。(Target detection and recognition, the occurrence of non-rigid deformation between the target point matching algorithm.)

傅 立叶变换是数字信号处理领域一种很重要的算法。要知道傅立叶变换算法的 意义，首先要了解傅立叶原理的意义。傅立叶原理表明：任何连续测量的时序或 信号，都 可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的 傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正 弦波信号的频 率、振幅和相位。 (The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. )
