matlab 滤波信号处理功能，消除确定性成分和拟合曲线。(matlab funtionFiltering signal processing function, eliminate deterministic component and fitting curve 。 )

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 .)

这个是整理之后的MATLAB函数大全，希望对MATLAB初学者有用(This is a MATLAB function Daquan after finishing the hope that useful to MATLAB for beginners)

说明：  层次分析法matlab程序及说明书，是指将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。(Analytic hierarchy process (AHP) matlab program and specification is a decision-making method that decomposes the elements related to decision-making into objectives, criteria, schemes and other levels, and carries out qualitative and quantitative analysis on this basis.)
