jpeg的实现方式

说明：  半桥高频变压器仿真，频率100KHZ，闭环系统(Half-bridge high-frequency transformer simulation, frequency 100 KHZ, closed-loop system.)

matlab hmm toolboxThe script dhmm_em_demo.m gives an example of how to learn an HMM with discrete outputs. Let there be Q=2 states and O=3 output symbols. We create random stochastic matrices as follows.

matlab实现PCA进行的人脸识别源程序，基本的功能实现，做为基础(matlab realize PCA for face recognition source code, the basic function of the realization, as a basis for)

用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，(Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images,)

用MATLAB仿真AD设计中的DNL和INL计算(AD Design using MATLAB simulation of the DNL and INL calculation)

This MATLAB code computes the covariance matrix of a random variable

convolution with overlap-add procedure

说明：  这是一个基于M/M/S类型的排队论仿真程序。M/M/S表示到达时间为负指数分布，服务时间为负指数分布，服务设备数量为S个的排队系统。 （1）到达模式：严格意义上讲是一个接着一个到达，而且到达时间间隔服从参数为mean_arr的负指数分布； （2）服务模式：服务台的数量为server_num,且每个服务台服务一个顾客的服务时间服从参数为mean_serv的负指数分布； （3）排队规则：满足先进先服务，服务快的先离开的规则。 (This is a based on the M/M/S types of queuing theory simulation program. M/M/S said time of arrival of the negative exponential distribution and service time for the negative exponential distribution, service equipment for the number of S-queuing system. (1) mode of arrival : a strict sense is a one followed arrived, but the inter-arrival time parameters mean_arr obey the negative exponential distribution; (2) mode : The number of help desk server_num. with each help desk services a customer service parameters mean_serv obey the negative exponential distribution; (3) queuing rules : first meet advanced services, the first to leave fast rules.)
