MATLABCODE1

说明：  一维光子晶体反射率的计算，可以用来制作相应的光子晶体，用来分波(One-dimensional photonic crystal reflectivity calculations can be used to produce the corresponding photonic crystal, for partial wave)

homework 3-5 is difficult

换热站计算及选型，非常有用，里面用的XLS编写的，直接用就可以～～～～～(Calculation and selection of heat transfer stations, very useful, which use XLS written directly on it ~ ~ ~ ~ ~)

说明：  针对多种光栅，传输谱反射谱进行仿真，同时对反射谱加入切趾函数抑制旁瓣，MATLAB仿真(For a variety of gratings, the transmission spectrum reflection spectrum is simulated, and the apodization function is added to the reflection spectrum to suppress side lobes, MATLAB simulation)

说明：  大电网的三相短路计算，不对称和对称等，实测可行！(Large power three-phase short circuit calculations, asymmetry and symmetry, the measured viable!)

This is the m file to read or uff file using matlab, uff file to generate. It is sometimes convenient to issue read, create, so that if someone put a data value.

本程序使用非负矩阵分解方法进行网络社区检测(detecting the community by using the NMF )

改进的ESPIRIT方法，性能更好，分辨率更高，是超分辨率估计(high resolution DOS esimation)

y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

相移光栅的反射谱和折射谱仿真，光纤长度、调制强度、相移等参数均可调(Phase shift grating spectral reflection and refraction spectrum simulation, fiber length, intensity modulation, and other parameters can be adjusted for a phase shift)
