Trace-seismic

本程序实现haar小波的变换，在图像去噪。压缩等方面有很大的帮助(This procedure to achieve haar wavelet transform, the image de-noising. Compression there is a great help)

平面桁架单元，力，长度，刚度，应力程序,使用matlab编制(plane truss force,length ,stiff,stress)

This runs the distribution loadflow for a radial distribution system, it is a matlab code

主成分分析方法在各个变量之间相关关系研究的基础上，用较少的新变量代替原来较多的变量，而且使这些较少的新变量尽可能多地保留原来较多的变量所反映的信息一种方法。(Principal Component Analysis in the relationship between the various variables on the basis of the study, with fewer new variables replace the original more variable, but made them less a new variable as much as possible to retain the original variables that reflect more information methods)

MATLAB语言在Java里的使用：详细介绍了相关的环境配置，MATLAB打包步骤，以及在Eclipse里使用Java调用资源包的全过程。含测试实例(MATLAB language used in the Java：details of the environment configuration, MATLAB package, and the use of Java resource bundles to call the whole process in the Eclipse. Containing the test case)

可以产生正弦信号和白噪声时域信号波形，以及混杂噪声的正弦波波形，信噪比可调(the sinusoidal signal can be generated when the white noise domain waveform, sinusoidal waveform, and the noise mixed SNR adjustable)

对信号进行分析，取得信号的频率，幅值等特性。利用MATLAB编程，界面友好(Analysis of the signal to obtain the signal frequency, amplitude and other characteristics. Using MATLAB programming, user-friendly)

最小二乘支持向量机，程序粘到command window里，设定 2 两个参数，可以更改，以达到最优化(igam=0.001 isig2=0.001 [gam,sig2]=tunelssvm({X,Y, f ,igam,isig2, RBF_kernel },... [0.001 0.001 10000 10000], gridsearch ,{}, leaveoneout_lssvm ) type= function approximation kernel= RBF_kernel model=initlssvm(X,Y,type,gam,sig2,kernel) model model=trainlssvm(model) Yt=simlssvm(model,Xt) )

matlab的S函数例程，是关于滑模变结构的(S function matlab routines, is about Sliding Mode Variable Structure)

说明：  快速ICA算法，在盲源分离中有很大的用处。(fast algorithm, the blind source separation is very useful.)
