软件工程的设计和开发文件，由于本人也不知道怎么回事，所以还请读者自己去斟酌，希望对你们有帮助！(software engineering design and development, because I do not know how, therefore, also invited readers to their own discretion, and I hope to have your help!)

I found this paper regarding to LPR interesting and I would like to share it.

利用Matlab提供的firhalfband函数设计阶数为16、通阻带容限为0.0001的半带滤波器。 仿真测试滤波前后的信号时域图，绘制滤波器的频率响应特性图。( Matlab provides firhalfband function design of the order number is 16, stopband tolerance of 0.0001 half band filter. simulation test before and after filtering signal time domain graph, drawing filter frequency response characteristics of the figure.)

拟牛顿法和最速下降法(Steepest Descent Methods)一样只要求每一步迭代时知道目标函数的梯度。通过测量梯度的变化，构造一个目标函数的模型使之足以产生超线性收敛性。这类方法大大优于最速下降法，尤其对于困难的问题。另外，因为拟牛顿法不需要二阶导数的信息，所以有时比牛顿法(Newton s Method)更为有效。如今，优化软件中包含了大量的拟牛顿算法用来解决无约束，约束，和大规模的优化问题。(The quasi-Newton method and the Steepest Descent Methods only require that each step iterations know the gradient of the objective function. By measuring the change of the gradient, constructing a model of the objective function is sufficient to produce superlinear convergence. This method is much better than the steepest descent method, especially for difficult problems. In addition, because the quasi-Newton method does not require information on the second derivative, it is sometimes more effective than the Newton s Method. Today, the optimization software contains a large number of quasi-Newton algorithm used to solve the unconstrained, constraint, and large-scale optimization problems.)
