MATLAB--hecheng

说明：  将quartus的仿真数据结果导入到matlab中进行后续的操作(Will Quartus results of the simulation data into matlab conducted follow-up operation)

电表数字检测，自己写的，用的是matlab语言(Meter digital testing, their written language using the matlab)

经验模态分解，matlab实现，用于信号的降噪处理，提取特征值处理等经验模态分解，这是用汉语注释的EMD程序，很不错的。％ 语法 ％ IMF = EMD(X) ％ IMF = EMD(X,..., Option_name ,Option_value,...) ％ IMF = EMD(X,OPTS) ％ [IMF,ORT,NB_ITERATIONS] = EMD(...) (This is annotated in Chinese EMD procedures, very good. Syntax IMF = EMD (X) IMF = EMD (X ,..., Option_name, Option_value ,...) IMF = EMD (X, OPTS) [IMF, ORT, NB_ITERATIONS] = EMD (.. .(Empirical mode decomposition, matlab, used in signal noise reduction processing, extraction of characteristic value processing, etc)

基于公交上下客的客流OD矩阵推算，与参考文献所推数据完全一致。代码完全独创，实用价值高。(Transit OD Matrix estimation based on Passenger boarding and alighting. )

对整个图像进行分块，再对每块进行像素点寻找，最后合并块。(cut the picture,then find the pixels which are demanded,finally merge them back to the picture)

用matlab中gui做一个普通的科学计算器,可以参考一下(through Matlab gui，a common scientific calculator was made , you can consult it)

说明：  矩量法求解海伦方程算例选择狄拉克函数为基函数和权函数 (Helen equation method of moments examples chosen Dirac function as basic function and weight functions)

matlab and communication system

说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)

本程序对于 循环统计量中存在的直扩信号进行检测，效果很好(This procedure for the circulation statistics that exist in DSSS signal detection, the effect of good)
