本案例为不等式约束最优化问题，采用罚函数法（内点法）。具体求解过程是用MATLAB编程求解的。(The Case for inequality constrained optimization problem using penalty function method (interior point method). Specific solution process is solved using MATLAB programming.)

从maxwell方程组出发，用平面波展开法推到出电磁波在光子晶体的本征方程。有例程(Starting from maxwell equations, plane wave expansion method to the electromagnetic waves pushed Eigenequation photonic crystals.)

在地震资料处理时，将su文件转换为segy文件，需要写道头和卷头，程序中有给出，其中一些读写segy文件的函数需要再行下载(When seismic data processing, the file is converted to segy su file, you need to write head and the volume header, the program has given some of which function to read and write files need to re segy download)

自编的几个关于数字信号基本运算的程序，由此可以大大扩展信号运算的自由性与简洁性。(wrote several digital signal on the basic operations procedures, It can be greatly expanded signal operation and the freedom of simplicity.)
