matlab相关教程，希望能给大家提供帮助，可以看看的资料(matlab tutorial, I hope to give help, you can see the information)

右边伸出的bar导航，IOS编程学习源码，很好的参考资料。(Bar navigation right out, learning IOS programming source code, a good reference.)

针对结构转角信息难以测量的问题，采用转角信息重构技术由随机子空间从振动信号中提取的结构平动位移估算结构转动位移，然后构建改进的单元损伤变量(Since it is difficult to measure the rotational responses of a structure, a technique was adopted to evaluate the approximate modal rotations with the modal displacements, which were extracted from structural vibrational signals with stochastic subspace identification, by static condensation and QR decomposition)

This is matlab code for stockwell transform as a time frequency distribution for feature extraction that was developed by Doctor stockwell

求一个40阶的雷米兹带通滤波器，并绘出两个滤波器的幅频特性图(Remez seeking a 40-order band-pass filter, and plot the frequency characteristics of two filters map)

算法由于提供了一个预测值,相对来说有简化.第五种方法,也就是ode45所得的精度最高尺度到了1e-18...简直可怕!一般很少有工程问题是它不能够满足的了,能够看出,解的差别在本问题里已经很明显了. (algorithm providing a predictive value, a relatively simplified. Fifth, ode45 is the highest accuracy of a scale of e-18 ... is simply terrible! it seldom works that asked that is not able to meet it in the can see that the solution of differences in the issues it is already very clear.)

ve-DYNA® 为用户提供了车辆动力学、车辆非线性行为的可配置仿真模型。用户根据自己的工程问题选择合适的车型（轿车，货车，拖车）和适当的版本（低级，标准，高级）就能实现不同的应用。用户基于模型就能开发自己的控制算法或者部件，然后通过离线仿真和硬件在回路仿真来进行检验和验证。只需要进行鼠标键盘的操作，就可以对种种的动力学问题进行分析，比如悬架动力学，车辆动力性或操纵稳定性。这样 就 能够减少昂贵而且费时甚至是危险的实车试验。可以在无人监控的情况下完成整个的测试、优化和系统验证 。本文为veDYNA软件的相关例程介绍。(ve-DYNA ® provides users with vehicle dynamics, nonlinear behavior can be configured vehicle simulation model. Users according to their engineering problems select the appropriate models (cars, trucks, trailers) and the appropriate version (low, standard, advanced) will be able to implement different applications. Users can develop their own model-based control algorithms, or parts, and then off-line simulation and hardware in the loop simulation to be tested and verified. Only for mouse and keyboard operation, it can analyze the various dynamics, such as suspension dynamics, vehicle dynamic performance or handling and stability. This can reduce the costly and time-consuming and even dangerous in real vehicle tests. No one can monitor the situation in the completion of the testing, optimization and system verification. This article related to software routines for the veDYNA introduction.)
