用matlab实现的svm程序实例，希望能对感兴趣的人有帮助(Achieved by SVM matlab instance, hoping to help people who are interested in)

已知信号的m(t)dsb-am调制 ~~~~~~~~~~~~~~~~~~~~~~~~~~··(dsb-am)

Decompose image into subbands (undecimated wavelet), denoise, and recompose again. fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig) im : image Nsc: Number of scales daub_order: Order of the daubechie fucntion used (must be even). block: size of neighborhood within each undecimated subband. noise: image having the same autocorrelation as the noise (e.g., a delta, for white noise) parent: are we including the coefficient at the central location at the next coarser scale? covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Javier Portilla, Univ. de Granada, 3/03 Revised: 11/04

说明：  差分进化基本算法的MATLABA实现。程序在MATLAB 7.0调试。(implement base defferential revelution with matlab 7.0. )

此程序实现一个模拟的雷达PPI显示界面，能显示雷达站的相关信息(this program produces a interpace about radar PPI, it can display radar station information)

Calculate the Fourier transform of certain pattern like circular aperture, rectangular aperture etc.

基于MATLAB图形用户界面GUI的中红外光谱处理软件，可对原光谱和其二维相关光谱方便画图(A Mid-Infrared Data Analysis Software(MIDAS-2010)based on MATLAB GUI.It is very convenient for drawing original spectral and its two dimensional correlated spectroscopy )

Robotics TOOLBOX The Toolbox provides many functions that are useful in robotics including such things as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots. Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf

使用EM算法，估计16QAM调制方式下的信噪比(EM algorithm using the estimated signal to noise ratio under 16QAM modulation)
