说明：  解方程的matlab源码，有问题的请大家说明(Solution of equation matlab source, there are problems please note)

将断层剖面划分为一组网格，并以固定的事件数或固定的扫描半径，计算每个网格点处的b值。然后用色彩表示断层面上b值的分布情况，从而反应断层的应力积累情况，便于地震学家分析该断层是否存在发震的可能(This subroutine creates a grid with spacing dx,dy (in degreees). The size will be selected interactively or grids the entire cross section. The b-value in each volume is computed around a grid point containing ni earthquakes or in between a certain radius. The standard deviation is calcualted either with the max. likelihood or by bootstrapping, when that box is checked. If not, both options can be assigned by the additional run assignment. Standard deviation of b-value in non-bootstrapping case is calculated from Aki-formula!)

这为一个通过频域重构方法获得ＳＡＲ信号点目标的ＭＡＴＬＡＢ仿真软件，是微波成像雷达领域的一个极好的软件(This is a reconstruction obtained by frequency domain SAR signal point target MATLAB simulation software, is the field of microwave imaging radar, an excellent software)

采用有限元法求解一维、二维抛物型方程，matlab编程(FEM for 1-D，2—D parabolic equation)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.
