some usefull matlab code to practice matlab

phase its about phase of a signal or imf that you can find it for another things also in this code you can fine the amplitude of a complex number

基于matlab建立的关于汽车轴的控制模型，包括轴的运动方程和模型的建立。其实在ADVISOR中可以找到，不过，用matlab2012版重新建立了。(Established based on matlab axis control on the car model, including axis motion equations and model. ADVISOR can be found in the fact, however, re-established with matlab2012 version.)

Flow to compute the incompressible flow in a lid driven cavity

Turbo码仿真程序。有Turbo码的编码，MAP算法，迭代译码，删余和没删余的。(Turbo code simulation program. Turbo codes have coding, MAP algorithm, iterative decoding, censored and no more than delete the remaining.)

MATLAB 很经典的案例分析，和 matlab 神经网络30个案例分析配套

说明：  最小二乘法的Matlab参数辨识程序（含实例）(Matlab least squares method of parameter identification procedures (including examples))

Pattern Recognision with matlab(Pattern Recognision)

使用MATLAB编写的qdudqz神经网络算法，本程序根据训练好的网络文件DNViuWY预测新的数据文件，得到算法的最差性能和最优性能，并绘制出预测数据和原数据的对比图。调试运行正常。 (Using MATLAB preparedqdudqz neural network algorithm, the program according to the trained network fileDNViuWY anticipating new data files to obtain the best performance and the worst performance of the algorithm, and draw out the comparison chart data and predict the original data. Debugging and running properly. )

说明：   通过模糊c-均值（FCM）聚类实现图像的分割。(Through the fuzzy c-means (FCM) clustering to achieve image segmentation. )
