目标检测（小目标或点目标检测，基于数学形态学的目标检测）(Target detection (small target or target detection, target detection based on mathematical morphology))

说明：  MATLAB命令大全 MATLAB help 的中文(MATLAB command Daquan MATLAB help the Chinese)

UKF Unscent Kalman Filter 算法(Unscent Kalman Filter)

Tutorial of filter: design a lowpass FIR filter of cutoff requency 0.3*pi. Plot the impulse responses h(n) and magnitude responses of the designed filters

说明：  matlab中完整实现分水岭算法的分割，效果很理想(matlab full implementation in the watershed segmentation algorithm, the effect is very satisfactory)

随机产生二进制序列，进行128QAM调制，画出星座图，通过加性高斯白噪声的信道，再画星座图，并计算误比特率。(128QAM modulate with MATLAB)

Forstner算子，摄影测量重要算子，用于提取兴趣点(Forstner operator, photogrammetry important operator, used for extracting points of interest)

说明：  该函数用来计算时间序列的最大Lyapunov 指数--Wolf 方法(The function used to calculate the time series of the largest Lyapunov index- Wolf method)

噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)

船舶扭振计算的例程，船的轴系较复杂，所以大多数例子都是关于船舶的！(an example of ship torsional vibration)
