这里面有很多的music算法仿真程序，一维经典music，ESPRIT 算法，Root算法，和二维面阵music算法,L型算法，空间平滑music，传播算法，以及现场测试程序。尤其是这个现场测试程序，理论与实践还是有一定的距离。这是一个居于现场实测实验的music算法，其与经典的music算法有一个很大的不同，是一个均匀四元阵两个信号的程序，对于一些在现场测试实验不能得到与经典算法理想的结果有很大的帮助。希望对实测实验的有帮助，自己摸索了很久。(music doa esprit L)

Wavelet denoising For using this code need to use signal toolbox and general toolbox in your matlab In the first part of this assignment, we asked to obtain a (black-and-white) digital image of size 512 by 512 and then generate noisy image by adding a Gaussian noise but under the condition of having SNR=20dB by select the suitable value of variance for Gaussian noise formula. Second step is performing wavelet denoising using the hard thresholding (Use the db 6 for four levels) in the condition of finding the optimal thresholding value of T in terms of the SNR obtained. It means that, we should find the highest SNR value by finding the suitable value for threshold. Then we asked to do the same process but this time using soft thresholding. Finally for the last part of question one, we should compare the results of the obtained SNR with the recommendations of 3*sigma for the hard thresholding and 3/2*sigma for the soft thresholding.

This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals. the calculated dispersion relation of the resistivity of a single band is saved as data file. to use the program, run g_E2.m(This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals.
