求解TSP问题的matlab程序，好用！！！(Matlab program for solving TSP problems, easy to use! ! !)

How the K-mean Cluster work Step 1. Begin with a decision the value of k = number of clusters Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following: Take the first k training sample as single-element clusters Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster. Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample. Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments. (How the K-mean Cluster workStep 1.

对初学者来说，泛函分析很难搞懂。这份资料就是关于泛函分析的，里面详细讲了泛函的来龙去脉。(For beginners, it is difficult to understand the functional analysis. This information is about the functional analysis, which details about the functional sequence of events.)
