这是根据汽车理论中的驱动力平衡基本方程所搭建的汽车行驶二自由度simulink仿真模型(this is a 2 degree dynamics simulating model under the matlab/simulink environment)

this is matlab code for hmm

对边界进行二次取样源码，用canny等算法提取一次边界后，点数过多，不利于描述形状，用这个代码可以实现二次取样。(The boundary of second sampling source, such as canny extraction algorithm with a boundary, too many points, which describe the shape, use this code can realize the second sampling.)

自己编写的小程序，实现高斯概率密度函数，希望对大家有帮助(to implement the gaoss density function)

关于分解的viterbi译码的matlab算法()

Rician fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening). Rician fading occurs when one of the paths, typically a line of sight signal, is much stronger than the others. In Rician fading, the amplitude gain is characterized by a Rician distribution.

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

由于Matlab R2012a 之后的版本中系统isrgb函数被移除了，特编此函数，用于判断图像是否为RGB格式。(To tell whether the image is the RGB format. )

小波包分析提取振动信号中的特征频率，与理论分析结果相比，用于建立主成分分析模型。( Wavelet packet analysis to extract vibration signal characteristic frequency, Compared with the results of theoretical analysis, Principal component analysis model for establishing.)

说明：  对萨德系统AN/TPY-2雷达的威力范围进行仿真计算。原创！！(The power range of SAD AN/TPY-2 radar is simulated. Original!!)
