一个很好带阻滤波器的设计，并给出了用来滤除工频干扰的实例(A good band stop filter and filter frequency is given to an instance of interference)

时频分布算法中的短时fourier变换和维格纳变换的程序。(Algorithm for time-frequency distribution of short-time fourier transform and Wigner transform procedures.)

说明：  提取线性预测倒谱系数的matlab程序，使用的是自相关法(Linear prediction cepstral coefficients extracted the matlab program, using the autocorrelation)

算法由于提供了一个预测值,相对来说有简化.第五种方法,也就是ode45所得的精度最高尺度到了1e-18...简直可怕!一般很少有工程问题是它不能够满足的了,能够看出,解的差别在本问题里已经很明显了. (algorithm providing a predictive value, a relatively simplified. Fifth, ode45 is the highest accuracy of a scale of e-18 ... is simply terrible! it seldom works that asked that is not able to meet it in the can see that the solution of differences in the issues it is already very clear.)

功率谱估计和信号频率估计方法 周期图法 BT法(Power spectrum estimation and the signal frequency estimation methods periodogram )

说明：  在Bialas與Karwan的第 解演算法 [13] 則是搜尋限制式解域中的端點，並且歸類為已搜尋端點集合、未搜尋端點集合、可行解端點集合、非可行解端點集合，再從可行解端點集合中找出使高階目標值最佳的端點。(Bialas and Karwan in the first solution algorithm [13] is the search for solutions in the domain of endpoint constraints, and the endpoints are classified as a collection of search, not search a collection of endpoints, the endpoint set of feasible solutions, non-feasible solution side point set, then the endpoint from the set of feasible solutions in order to identify the best target endpoint.)

一个KNN的matlab程序，供感兴趣的人士学习(A KNN matlab program for those interested in learning)

关于matlab的方法及实例，有效，全面，是数学建模的好帮手(about matlab)

本matlab程序用乘子法求解多元模型的最小值（给出初始点和精度要求条件）。(The matlab program for solving the minimum multivariate model using multiplier method (given initial point and precision conditions).)
