Solution for some problems in Codeforces

我编的用于晶体的J-O 参数，对于稀土分析的研究者很有用啊(crystal series for the J-O parameters for the analysis of rare earth researchers useful ah)

在vc.net中调用Matlab生成的COM组建实现曲线拟合。(in vc.net Calling Matlab generated COM form and curve fitting.)

交错网格声波方程正演模拟，PML吸收边界，比较适合刚刚接触的学者。交错网格有限差分地震波场计算，二维的声波正演，利用空间10阶，时间2阶。(The CalCulation of the SeismiC Wave一 fieldwith Staggered-grid Finite difference Sheme)

Bin packing problem belongs to the class of NP-hard problems, like the others that were discussed in previous articles. The task is to pack a set of items of different size into bins of fixed size in such way that minimal number bins is used. Depending on the requirements, bin packing can be single-dimensional (1D) or multi-dimensional (2D, 3D...)

说明：  LDPC的编码和译码程序 采用vc及matlab(LDPC coding and decoding process, and matlab using vc)

说明：  既可以用于高压输电网的潮流解算，又可以用于低压配电网的潮流解算，还可以同时解算输电网 加配电网的混合潮流问题,程序为PQ 分解法.(Both the trend for high-voltage transmission grid solver, but also the trend for low voltage distribution network solver, solver can also increase with the power transmission grid hybrid power flow problem, the program for the PQ decomposition.)

经典功率谱估计，BT法、Welsh法、中值滤波法(matlab BT Welsh)

让ARToolKit支持MQO模型的必须头文件，GLMetaseq.h(Let ARToolKit support MQO model must header files, GLMetaseq.h)

利用有限差分软件Flac3d生成人工地震波，并用于岩土工程动力分析(Using finite difference software Flac3d generate artificial seismic waves, and for dynamic analysis of geotechnical engineering)
