实现辅助模型最小二乘和经典最小二乘的仿真算法比较，有辨识误差比较图(The comparison of the simulation algorithms between the least squares and the classical least squares of the auxiliary model has the error comparison diagram of identification.)

此程序为随机子空间法的模态参数识别程序，可用来识别模态参数（模态频率，模态振型，阻尼比）(This program is a stochastic subspace method modal parameter identification program that can be used to identify modal parameters (modal frequency, mode shape, damping ratio))

针对集装箱倒箱问题，研究出口箱在码头堆场的翻倒过程(the block relocation problem in container terminal yard)

简单介绍就是一个使用Mathematica进行二维流场模拟的例子，你还可以自己控制各项参数进行调整。展示文件和原始代码都传上来了。 A 2D fluid velocity field is represented using streamlines. A streamline is tangent to the velocity field everywhere. Streamlines are plotted for the velocity field generated by the components of the velocity vector. You can vary the values of the coefficients, exponents, and constants of each component u and v of the velocity vector. You can restrict the range with the controls at the top.
