该压缩包包括两个m文件，一个为IEEE推荐的UWB信道模型的matlab仿真程序，另一个为对应的RMS时延扩展计算，并附带了一个文档文件作说明。(The archive includes two m files, one for the IEEE UWB channel model recommended by the matlab simulation program, and the other for the corresponding calculation of RMS delay spread, and comes with a document file for instructions.)

改压缩包包含了三个程序 分别是对坐标对称的自由梁的模态频率和色散关系的求解(Reform package contains three programs are free modal frequency of the beam coordinate symmetry and the solution of the dispersion relation)

该程序主要完成jeffcott转子圆周碰摩故障仿真，包括设置初始条件，转子系统参数等(rub-impacting of rotor)

使用MATLAB对MIMO系统进行辨识，其中有各种算法仿真算例，N4SID，针对多变量系统的一种识别算法(MOESP (Multivariable Output-Error State sPace) is a deterministic method to identify linear time invariant systems. The MOESP method developed by M. Verhaegen and P. Dewilde is based on the LQ decomposition of Hankel matrix formed from input-output data, where L is lower triangular and Q is orthogonal. A Singular Value Decomposition (SVD) can be performed on a block from the L (L22) matrix to obtain the system order and the extended observability matrix. From this matrix it is possible to estimate the matrices C and A of state-space model. The final step is to solve overdetermined linear equations using the least-squares method to calculate matrices B and D.)
