matlab关于主成分分析的代码，使用于经济医疗等分析(a program code on matlab of principal component,it s used in economic,healthy and so on.)

计算弦长为L=8m、相对厚度为0.12的对称儒科夫斯基翼型受到的摩擦阻力和摩擦阻力系数，附面层厚度分布（附报告）(Calculated chord length L = 8m, the relative thickness of 0.12 Ru Khodorkovsky symmetric airfoil subject to friction and friction coefficient, boundary layer thickness distribution (with report))

一个菜单界面，分别用菜单命令来绘制原数据曲面图，线性插值，最近点插值，3次多项式插值，3次样条插值后的图形，每次插值都可以在同一图形界面下比较插值前后图形。(A menu interface, respectively, using the menu command to map the original data surface map, linear interpolation, nearest point interpolation, polynomial interpolation 3 times, 3 times after spline graphics, interpolation can be per- under the same graphical interface graphics compared before and after interpolation.)

《matlab应用大全》赵海滨编著，清华大学出版社，主讲数组与矩阵分析(The application of matlab Zhao Haibin compiled, tsinghua university press, speaker array and matrix analysis)

对轴承故障振动信号的matlab小波分析程序，能完成对故障特征频率的提取(Of bearing fault vibration signals matlab wavelet analysis procedures, can finish on the fault characteristic frequency extraction)

2D傅立叶变换，上课的小作业，包含报告和源码(2D Fourier transform, the small school assignments, reports and source code that contains)

说明：  提供两个点坐标，可以利用本程序，计算两点距离，简单好用。(Coordinates of two points, you can use this procedure to calculate the distance to two points, easy-to-use.)

自己编的使用小波实现的纹理图像分割，具体过程是先对图像进行三级小波分解，每级都对系数聚类并指导下一级分类，分割效果较好~ (own addendum to the use of wavelet achieve the texture image segmentation, specific process is the first image wavelet decomposition three each of the levels are right and clustering coefficients under the guidance of a classification, segmentation better ~)

说明：  插值和拟合算法实验源代码，希望给大家带来帮助。(Interpolation and the fitting method experimental source code, hope to bring you help. )
