Greedy Group Sparsity Promoting Optmization

this programe is a simulation of OFDM using FFT

说明：  这是一个用于数值分析的MATLAB程序集合，里面包含了一些常用的数值分析程序。(There are many programs about numerical analysis written in Matlab language.)

Input data is the MS Excel file, where the table of nodes, table of elements, nodal external loads vector and boundary conditions are stored. After running the mabs2d.m file on the Command Window, the program calculates the stiffness matrix in local coordinates kiL (element i). Once the transformation matrix associated to the element is obtained, the stiffness matrix in global coordinates kiG is also calculated. The table of connectivity is automatically generated for the assembly process and then computes the complete stiffness matrix of the structure.

该程序很好解决了，将两个矩阵交叉相加的结果取出，直接相加的结果所对应的行省略. 另外一个是DOA估计的程序。(It is good for solving the two matrix for cross adding,and delete the direct adding.)

MCMC based Ising model simulation

对三路信号进行分离，基于峭度和基于负熵的独立分量分析（ICA）(The three way signal separation, based on the kurtosis and independent component analysis (ICA) based on negative entropy )

光子晶体带隙结构, 以及有限周期情况下能谱不连续性的情况(Photonic band gap structure, and the case of a limited period photonic crystals energy spectrum of discontinuity . )

用于Matlab的hispice仿真程序， 图形界面(Hispice for the Matlab simulation program, a graphical interface)

说明：  计算mfcc的函数，mfcc在音频分类中相当重要(Mfcc function calculation, mfcc very important in the audio category)
