偏分方程的MATLAB解法(对matlab的pde工具箱，从图形用户界面入手，对各种典型方程和应用实例逐个作了计算和分析)(MATLAB Solution of partial differential equation (pde on the matlab toolbox, starting from the graphical user interface, a variety of typical equations and application examples have been calculated and analyzed individually))

利用matlab中傅里叶变换进行函数频谱分析的程序。亲测好用！(Fourier transform using matlab function spectrum analysis procedures. Pro-test easy to use!)

我编写bposs的神经网络应用程序，第一次上传(of neural network applications, the first upload)

matlab 滤波信号处理功能，消除确定性成分和拟合曲线。(matlab funtionFiltering signal processing function, eliminate deterministic component and fitting curve 。 )

Speech compression using Linear Predictive Coding. LPC is the oldest and the most basic of modern speech coders. Its a lossy scheme. Playback quality isn t preserved in the process but it can be used in low bit-rate systems.

用matlab计算并成图形的电路设计中幅频=相位响应图 ，也可为设计计算带通滤波器的中心频率以及Q值提供参考(Using matlab to calculate and graphics into the circuit design of amplitude and frequency = phase response plans can also be calculated for the design of band-pass filter center frequency and Q value to provide reference)

匹配滤波器（自己写的随机信号作业，凑合着还算够用吧）(matched filter (himself wrote the random signal operations, make do with it fairly enough))

采用RGB+K-means对路标进行提取，效果十分不错。(RGB+ k-means is adopted to extract road signs, and the effect is very good.)

k -medoids algorithm is a clustering algorithm related to the k -means algorithm and the medoidshift algorithm.

基于非线性动力系统的无迹卡尔曼滤波matlab程序(onlinear state estimation is a challenge problem. The well-known Kalman Filter is only suitable for linear systems. The Extended Kalman Filter (EKF) has become a standarded formulation for nonlinear state estimation. However, it may cause significant error for highly nonlinear systems because of the propagation of uncertainty through the nonlinear system. The Unscented Kalman Filter (UKF) is a novel development in the field)
