Analog clock simulation in Matlab

国外计算机科学教材系列，模式识别第四版课后习题部分matlab源码，李晶皎，王爱侠等译(Foreign computer science textbook series, the fourth edition of after-school exercise part of pattern recognition matlab source, Jiao Jing, Wang Aixia translated)

matlab对一幅图像，采用半径值为20、80、200的截止频率进行理想低通滤波，观察其结果。要求给出原图像及相应的付利叶频谱图和滤波结果(For an image, using the radius value of the cutoff frequency 20,80,200 ideal low-pass filter to observe the results. Required to give the original image and the corresponding Fourier spectrum and filtering results)

the ELM method is a learning technique, used to train a system

background subtraction using matlab

风力机模型 通过matlab simulink建立的,现在这种资太少了(wind turbine model through the establishment of the Matlab Simulink, which is now too little funding)

Noise estimators for MRI data Toolbox Several methods to automatically estimate the level of noise in single- and multiple-coil MRI

用Baum-Welch算法来迭代估计一个隐马尔科夫模型（HMM）的初始状态概率分布以及其状态转移概率矩阵。其中文件有mainfile_B_W.m为主函数，Baum_Welch.m为Baum-Welch算法迭代函数，Forward_variable.m与Backward_variable.m与Gamma_variable.m与Ksi_variable.m是需要计算的四种因子，B_pdf.m为混淆散射概率密度函数。(It s Baum-Welch algorithm for iteratively estimating the initial states probability distribution and state transition probability matrix. In the folder, "mainfile_B_W.m" is the main function, and "Baum_Welch.m" is the iteration Baum-Welch function. Also these four file "Forward_variable.m " "Backward_variable.m" "Gamma_variable.m" "Ksi_variable.m" are used for calculating crucial factors. "B_pdf.m" is the emission probability distrubution function.)

Not mine code, but very usefull!
