此为BP感知神经分类器,自己写的.有须要的请下载,很不错的.(this perception of BP neural classifier himself wrote it. The need to please download, very good.)

菲尔德网络知识，对神经网络只是大大的补充，该算法应用很广。(Rumsfeld network knowledge, the neural network is greatly supplement, the algorithm is widely used.)

在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)

本程序按照胡广书《现代数字信号处理》书中的谱估计的内容仿真了各种经典谱估计方法以及现代谱估计方法（周期图法、BT法、welch法、自相关法、修正的协方差法、burg法），因为是课程作业，因此逻辑上写得十分简洁，适合初学者参考。(The program in accordance with the Hu-book of modern digital signal processing book spectral estimation simulation the various classical spectrum estimation methods, as well as the modern spectral estimation methods (periodogram, BT France, welch method, auto-correlation method, the modified covariance method , burg method), because the course work, so logically written very simple for beginners.)

伪速率脉冲调制器的稳定性分析，通过绘制系统的Nichols图，分析柔性振动对主轴的影响(the stability anslysis of pseu-speed pusle modulator)

多变量高斯过程样本的产生，用matlab编写的(Multivariate Gaussian process for selecting the samples, prepared using matlab)

用matlab实现的心电数据的去除基线漂移和去噪功能，方便大家使用(Implemented with the matlab ECG baseline drift removal and denoising function to facilitate the people to use)

说明：  匈牙利算法源码，封装为函数，可以直接调用，可以运行(Hungarian algorithm source code, encapsulated as a function, can be called directly, can be run)

1) 编制通用的二值形态学运算（腐蚀和膨胀、开、闭和击中击不中变换）函数。 2) 函数可以处理不同的变换形式和不同类型的结构元素。 (simple functions of imopen imclose .etc)
