这段程序是关于图像分析之边界图、轮廓图、直方图(This program is about the image of the boundary map, contour maps, histograms)

attached file contain two algorithm for classification.K_means and K Nearest Neiborhood. and related m_filles in matlab

一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values ​ ​ is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

实现地震叠前三参数反演（纵波速度、横波速度、密度）(prestack seismic inversion (compressional wave velocity, shear wave velocity, density))

系统参数变化，用集合卡尔曼滤波器估计其变化(System parameters used to estimate the changes in the ensemble Kalman filter)

交错并联型双反激逆变器的saber仿真文件，自己做的一个项目的前期方案论证、原理验证的文件，做电力电子的朋友都知道它的好。(Interleaved dual flyback inverter saber simulation files, pre-program yourself to do a demonstration project, the principle of verification of documents, power electronics make friends all know it s good.)

迭代学习程序，用迭代实现一个简单的控制，结果表明控制效果十分好(Iterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hard！Iterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hardIterative learning process in matlab，a simple case，so easy，use a short method，how i need to write，so hard)

说明：  matlab经典教程，很全面，非常适合初学者。(matlab classic tutorial, very comprehensive, very suitable for beginners.)

说明：  通过设定个数，可以获取到重合度最高的几条直线在变换域中的几个点！(By setting the number, you can get to the highest degree of coincidence a few lines at several points in the transform domain!)

可有效计算各类熵值，信息熵、样本熵、谱熵计算，与其他程序相似(It can effectively calculate all kinds of entropy, information entropy, sample entropy and spectral entropy, similar to other programs.)
