用于相机标定的matlab工具箱，能够通过输入的一系列标定板图像信息，获取相机内参(the toolbox of Camera Calibration)

最新、最全“高阶谱分析工具箱”，包括全部教程和DEMO.(There is much more information in a stochastic non-Gaussian or deterministic signal than is conveyed by its autocorrelation and power spectrum. Higher-order spectra which are defined in terms of the higher-order moments or cumulants of a signal, contain this additional information. The Higher-Order Spectral Analysis (HOSA) Toolbox provides comprehensive higher-order spectral analysis capabilities for signal processing applications. The toolbox is an excellent resource for the advanced researcher and the practicing engineer, as well as the novice student who wants to learn about concepts and algorithms in statistical signal processing. The HOSA Toolbox is a collection of M-files that implement a variety of advanced signal processing algorithms for the estimation of cross- and auto-cumulants (including correlations), spectra and olyspectra,bispectrum, and bicoherence, and omputation of time-frequency distributions. Based on these, algorithms for parametric and non-parametric blin)

永磁无刷直流电机matlab/simulink模型及相关代码，使用了模糊控制对电机进行了调速。(Permanent magnet brushless DC motor matlab/simulink models and related code, the use of fuzzy control of the motor speed.)

介绍了一种基于VB 后台调用ANSYS和MATLAB进行设计计算的方法。通过借助VB设计的参数化输入界面， 调用APDL编写的模型分析程序和MATLAB编写的可靠性计算程序，实现了在用户界面上以可视化的形式显示计算结果功 能，并应用于铁路接触网设计的可靠性计算中，结果显示证明了计算软件的可行性和实用性。(Describes the background of a call based on ANSYS and MATLAB VB design calculation. VB by using the design parameters of input interface, called APDL model prepared by the procedures and the reliability of computer program written in MATLAB, implementation in the user interface to visualize the results in the form of display features, and design used in railway catenary the reliability of the calculation, the results proved the feasibility and practicality of computing software.)

本例是使用kalman filter作为状态观测器，对直流无刷电机的状态进行观测。从结果可以看出，对状态估计的效果非常的好(This example is the use of kalman filter as an observer state, the state of brushless DC motors were observed. As can be seen the results of state estimation of the effect is very good)
