esprit 旋转不变技术来估计波达方向 最基本算法，能估计出波达方向，但特征值较难估计，有误差，按照现代通信原理最基本算法matlab编码。(esprit ESPRIT DOA estimates the basic algorithm can estimate the DOA, but difficult to estimate eigenvalues, margin of error, according to the basic principles of modern communication matlab coding algorithm.)

kalman 演示程序 是kalman 滤波器MATLAB仿真(kalman filter smulation )

基于MATLAB 的语音信号频谱分析与去噪研究 1、通过Matlab读入语音信号，进行频域分析 2、绘制语音信号频谱； 3、设计滤波器并进行滤波； 4、加噪，对比语音信号波形和频谱(Research on speech signal spectrum analysis and denoising based on MATLAB 1, read the voice signal through Matlab and analyze it in frequency domain. 2, draw the frequency spectrum of speech signal; 3. The filter is designed and filtered. 4. Add noise and compare the waveform and spectrum of speech signal)

矩形光栅衍射效率的一般表达式的Matlabf仿真模拟(The general expression of rectangular grating diffraction efficiency Matlabf simulation)

说明：  用matlab实现的K2算法，需要用到贝叶斯网络工具箱(K2 algorithm implemented with matlab)

说明：  三篇关于MATLAB，模糊PID控制，液位控制与仿真的文章(3 on MATLAB, Fuzzy PID control, level control and simulation of the article)

分析chirp信号的改进fft算法，该FrFT算法是从matlab论坛中的算法，尝试后可用(Improved FFT algorithm for analyzing chirp signals)

this is matlab code for estimating the static linear system with Least Squre that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.
