KMEANS Trains a k means cluster model.CENTRES = KMEANS(CENTRES, DATA, OPTIONS) uses the batch K-means algorithm to set the centres of a cluster model. The matrix DATA represents the data which is being clustered, with each row corresponding to a vector. The sum of squares error function is used. The point at which a local minimum is achieved is returned as CENTRES.

Hybrid Monte Carlo sampling.SAMPLES = HMC(F, X, OPTIONS, GRADF) uses a hybrid Monte Carlo algorithm to sample from the distribution P ~ EXP(-F), where F is the first argument to HMC. The Markov chain starts at the point X, and the function GRADF is the gradient of the `energy function F.

a screen handling program to provide a flashing message. You will have to design a screen layout for where messages are placed on the screen. You will also have to consider when to delay the program in order to give the user time to read the messages. That is, the program will use the curses library, signals and the sleep function.

1.. 需要jdom.jar和bsf.jar,否則無法跟spring整合. 2.. dwr生成的javascript函數(shù)會(huì)自動(dòng)加一個(gè)回調(diào)函數(shù)的參數(shù),如原來的函數(shù)是checkExist(String name),那么生成的javascript函數(shù)是checkExist(callbackFunc,String name). 3.. 注意回調(diào)函數(shù)只能有一個(gè)參數(shù),就是服務(wù)器的返回值,如function(messFromServer),這里messFromServer是該操作在服務(wù)器上的返回值. 4.. util.js里面有很多有用的方法,最好熟悉一下. 5.. convert并不是必須的,只有你的函數(shù)需要傳遞非基本數(shù)據(jù)類型的數(shù)據(jù)時(shí)需要此項(xiàng). 我需要增強(qiáng)的,dom操作,javascript

This folder has some scritps that you may find usefull. All of it comes from questions that I ve received in my email. If you have a new request/question, feel free to send it to marceloperlin@gmail.com. But please, don t ask me to do your homework. Passing_your_param0 This folder contains instructions (and m files) for passing you own initial parameters to the fitting function. I also included a simple simulation script that will create random initial coefficients (under the proper bounds) and fit the model to the data.

Image Compression A collection of simple routines for image compression using different techniques. 圖象壓縮的不同方法 BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.
