通过运用粒子算法来求出一个复杂的函数的最优解，并运用3维仿真方法将它很好的仿真出来！(Particles through the use of a complex algorithm to find the optimal solution function and the use of three-dimensional simulation of a good simulation of it out!)

实现了用burg方法进行谱估计,输出有系数矩阵，方差，各阶预测误差等等(it realize the Spectral Estimation using the methed of burg.)

说明：  最小化l1范数的Matlab代码。求解模型为： min lambda*|x|_1+||A*x-y||_2。其中，|x|_1表示x的1-范数，||*||_2表示2-范数。该模型在稀疏成分分析、压缩传感器等领域有广泛的用途。( l1-Regularized Least Squares Problem Solver l1_ls solves problems of the following form: minimize ||A*x-y||^2+ lambda*sum|x_i|, where A and y are problem data and x is variable (described below). )

recnstitution重构相空间，在非线性系统分析中有重要的作用 (recnstitution reconstructed phase space, in the analysis of nonlinear systems plays an important role in the)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization procedures, using Matlab to achieve, is very simple.)

基于bp网络的最大误差逆向传播算法的实现(Maximum error back- propagation algorithm implementation based on BP network)

说明：  matlab求解vrpsd问题,解压可运行(HGA-for-VRPSD, The VRP is a well known integer programming problem which falls into the category of NP Hard problems, meaning that the computational effort required to solve this problem increases exponentially with the problem size.)

利用求语音信号倒谱的方法，对语音信号进行基音检测，并绘制出波形图。(Use for speech signal spectrum method of fall, the speech signal pitch detection, and rendering the waveform figure.)

利用LQR方法计算反馈增益，没什么好说的，看看就知道了，也许有挺大作用呢(LQR calculated using the feedback gain, and there is nothing more to be said, look at the know, it may be Tingda role?)
