MATLAB MODEL OF MODIFIED SEPIC CONVERTER WITH MAGNETIC COUPLING

去趋势波动分析的开发程序，共享给大家，谢谢。(Detrended fluctuation analysis of the development process, for everyone to share, thank you.)

Plot the 2D Multivariate Gaussian function when mean vector and covariance matrix are provided

本算法程序基于实测汽轮机振动信号进行了测试及性能分析。理论分析及仿真结果表明，AR模型谱估计算法在阶次合适的情况下，能够取得较好的方差及分辨力性能，适合于振动信号的功率谱估计，且AIC准则为确定合理的模型阶次提供了有效依据。(This algorithm based on the measured turbine vibration signal testing and performance analysis. Theoretical analysis and simulation results show that, AR model spectrum estimation algorithm in appropriate circumstances the order, the variance can achieve better performance and resolution, suitable for vibration signal power spectrum estimation, and the AIC criterion to determine a reasonable model order provides an effective basis.)

说明：  用牛顿迭代的方法，编写程序，是函数迭代的效率提高，比一般的迭代法要好很多(By Newton iteration method, the preparation procedure is to improve the efficiency function iteration, iterative method than the average much better)

1.二值图像的fft分析 2.显示频谱图像，频谱的零频率系数被移到频谱中间 3.填充矩阵填充后的情况比较 4.绘图直观形象(1. Binary Image fft analysis 2. Image shows the spectrum, Spectrum coefficient of zero frequency spectrum has been moved to the middle three. Filled Filled matrix compared to the situation after four. Mapping visual image)

遗传算法工具箱，还有遗传算法需要的全部函数，来之不易(Genetic algorithm toolbox, as well as all the required functions of genetic algorithms, hard-won)

Lamb波的频散曲线，利用matlab编制了导波曲线，为导波检测模态选取提供了技术工作(Frequency dispersion curve of Lamb wave The guided wave curve is compiled by MATLAB, which provides technical work for the selection of guided wave detection mode.)

本程序利用球形不变随机过程法模拟产生服从瑞丽分布的海杂波，适合实验室环境下做为海杂波的输入信号。(The program uses the same random process simulation of spherical produce the distribution of sea clutter obey Ruili, suitable for sea clutter under laboratory conditions as the input signal.)
