谱估计的music算法，比较典型的谱估计方法，研究了半天才写出来的哦(The music spectrum estimation algorithm, a typical spectral estimation method to study for a long time to write it out, oh)

机械结构的matlab仿真很实用 计算结构的加速度速度等等(Matlab simulation of the mechanical structure is very practical computing structure acceleration speed, etc.)

using the maping and composite method to calculate the integration of exp(-x2/2)

QPSK调制解调，可以用于验证QPSK的仿真效果以及图形对比，可以很直观的看出效果。(QPSK)

说明：  一个从甲苯中萃取笨酸的化工过程的模拟，并且可以改变萃取级数，供用户学习(A acid extracted from the toluene chemical process simulation, and extraction stages can be changed for the user to learn)

隐半马尔可夫模型，只要替换原有的参数就能计算。可以用于模式识别，剩余寿命预测等(Half hidden markov model, as long as replacing the original parameters can be calculated. Can be used in pattern recognition, the residual life prediction, etc)
