这是电网、理论中实现矩阵快速变换的程序代码，附有使用说明书，技术说明(This is a grid, matrix theory, to achieve rapid transformation of the program code, with the use of brochures, technical notes)

说明：  进行哈夫曼编码，并元素的码字，平均码长等(for Huffman coding, and elements of code words, the average yards long)

this code is estimate dyley time .

input file of ode 45

完整的决策树算法，训练决策树，修剪决策树(机器学习)(decision tree)

层次分析法，是matlab编写的，仅作分享之用(AHP(analytic hierarchy process))

分别用Kmeans FCM和dbscan算法进行聚类比较，内附UCI数据，可以进行验证(Respectively Kmeans FCM clustering algorithm and compare dbscan, enclosing UCI data that can be verified)

实现haffuman编码的功能，可以正确运行仿真并实现正常的输出(Encoding functions to achieve haffuman)

A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.
