arima时间序列模型，对一个序列进行也测(arima time series models, also measured on a sequence)

时程积分程序，给定结构激励，计算结构动力响应。(Time integration process, given the incentive structure, dynamic response of structure.)

Code to run the Non-negative Matrix Factorization algorithm as presented in the Lee, Seung 1999 Nature paper.

说明：  PPC上面类似Matlab的语言环境，希望有pda的同学们喜欢(PPC above language similar to Matlab environment, and hope to have the students like pda)

The smooth particle hydrodynamics (SPH), the diffuse element method (DEM), the element-free Galerkin method (EFGM), the reproducing kernel particle method (RKPM), the moving-particle semi-implicit method (MPS) are among others. However, it seems that these meshless methods have not succeeded in replacing the FEM analysis completely, while they show excellent performance in several special fields.

齿轮的一个构建文件，matlab真的很厉害哈，我要好好学 恩恩(A build file gear, matlab really very powerful Ha, I must learn Blessings)

frequency synchronization for ofdm

说明：  这个是基于非测距无线传感器网络定位算法的仿真(This is based on the non-distance localization algorithm in wireless sensor network simulation)
