使用C 语言编制Mex算法程序，对于提高算法的性能有很大帮助。 希望该文档能帮助大家进入matlab 和 c 语言之间互动的世界，也期待你编制更多的原创程 序奉献给研学论坛，尤其是混沌和分形版面(The use of C language algorithm Mex procedures, for improving the algorithm performance of much help. I hope the document will help us to enter the matlab and c language of interaction between the world, and also look forward to your program to produce more original Forum dedicated to research, especially the chaotic and fractal layout)

训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

对标幺化感应电机的控制，依次分块地对磁通，转矩，转矩设计控制器，并对模型简化和未简化的情况做对比，适合于对感应电机控制各个环节的控制有更深的理解。(Induction motor control, in turn block the flux, torque, torque design of the controller, and the model is simplified and not simplified contrast, is suitable for the control of all aspects of a deeper understanding of the induction motor control. The outcome of the study in the experimental class)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)
