PURPOSE: GARCH(P,Q) time series simulation

旋转子空间程序，实现DOA定位，可用于DOA的学习使用(Subspace rotation procedures to achieve DOA positioning, can be used to study the use of DOA)

自适应波束形成（智能天线）的MATLAB代码仿真程序(Adaptive beamforming (smart antennas) code of the MATLAB simulation program)

这是matlab的50道练习题，可以方便初学者进行自我检测，基本上这些题会做，matlab也就没有多大问题了。(This is a matlab 50 exercises, beginners can easily be self-testing, basically these questions will do, matlab there is no big problem.)

该函数计算单元的刚度矩阵，输入弹性模量E、横截面的惯性矩I和梁单元的长度L，输出单元的刚度矩阵(Computational unit stiffness matrix)

小波算法，用于对红外光谱或者拉曼光谱数据进行降噪和去背景等处理。(Wavelet algorithm for the Infrared or Raman spectral data to background processing and noise reduction.)

改程序能进行空间梁单元刚度矩阵的生成，可在此基础上进一步进行常用有限元计算的开发。(beam-element-matlab)
