matlab做的关于最短路问题的的实现。包含了2个课件。可直接使用。 (Matlab to do to achieve on the shortest path problem. Consists of two courseware. Can be used directly.)

混频系统分析，包括零极点图、单位冲击响应和频率响应(Mixing system analysis, including pole-zero map, unit impulse response and frequency response)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.

电力电子matlab仿真，是电力系统仿真必备软件，内涵大量源代码(Power Electronics Matlab simulation, power system simulation necessary software, the connotation of a large number of source code)

In matlab, after creating the figure you need to save it as a pdf format for various of purposes. in this function I illustrated how you can save your figure in pdf format,

感知器算法的基本思想是，对初始的或迭代中的增广权矢量 ，用已知的训练模式检验它的合理性，当不合理时，对其进行校正，校正方法实际上是最优化技术中的梯度下降法，上传的是用matlab解决感知器问题。(The Perceptron Algorithm The basic idea augmented weight vector of the initial iteration, the known training mode to test it reasonable, unreasonable, its correction, the correction method is actually the most optimization techniques the gradient descent method, upload matlab to solve perception problems.)

卡尔曼滤波器的NNF算法,可以用来对飞行器的轨迹进行预测(Kalman filter using the nearest neighbor filter for data association algorithm)

因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis can be found in many variables hidden with a representative factor. The same nature of the variables included in a factor, can reduce the number of variables, but also to test the relationship between the hypothesis.)
