matlab code for bitstuffing in HDLC protocol

:运用牛顿动力学方法对单级倒立摆系统进行了数学建模,并对基于经典控制理论的PID控制方 法、基于最优控制理论的LQR控制方法,以及基于模糊控制理论的模糊控制方法进行了仿真对比分析 研究,其分析结果对该方向的研究具有理论指导意义(: Application of Newton)

旅行者问题（travelling salesman problem）算法()

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )

实现了parzen窗的方窗和高斯窗形式算法，输入只需输入样本，样本个数和窗宽能的出其概率密度函数(A window algorithm for Parzen windows)

基于非线性扩展卡尔曼滤波的Matlab程序(The extended Kalman filter can not only estimate states of nonlinear dynamic systems from noisy measurements but also can be used to estimate parameters of a nonlinear system. A direct application of parameter estimation is to train artificial neural networks. This function and an embeded example shows a way how this can be done.)
