在MATLAB里，对数据进行拟合，在双对数坐标下，看数据是否符合幂律分布，求出幂指数，并绘出图形。-In MATLAB, the pairs of data fitting, in double logarithmic coordinates to see whether the data meet the power-law distribution, find the power index, and draw the graph.

功率谱分析 matlab 解压后 使用时在matlab里set path ，该文件不用修改，运行后plot即可得出图形-power spectrum analysis

power_thermal.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常-power_thermal.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures

ECG data and includes source code written in MATLAB, Virtual power wireless sensor network coverage, The signal spectral analysis and filtering.
