实现拉格朗日插值，和用拉格朗日插值拟合函数(Lagrange interpolation to achieve, and the fitting function with the Lagrange interpolation)

说明：  这是一个关于OQPSK的Matlab程序 这是一个关于OQPSK的Matlab程序 (This is a OQPSK the Matlab program is a program of OQPSK in Matlab)

语音处理矢量量化技术，用于从一帧语音中提取特征矢量 相当有用(in speech signal process vector quantization technology with matlab code)

太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)

系统辨识作业，仿真比较OE模型 ARMAX模型 和ARX模型的便是效果，内涵ppt。(System identification operation, the simulation model compared OE and ARX model ARMAX model is the effect, meaning ppt.)
