用最速下降法求解多维函数的极值 function [x,minf]=minFD(f,x0,var,eps) 目标函数：f 初始点：x0 自变量向量：var 精度：eps 目标函数取最小值时的自变量值：x 目标函数的最小值：minf( With the steepest descent method for solving the multi-dimensional function of the extreme value function [x, minf] = minFD (f, x0, var, eps) target function: f Initial Point: x0 argument vector: var Accuracy: eps target function takes the minimum value of the independent variable values: x minimum target function: minf)

应用蒙特卡罗模拟方法计算期权价格 统计模拟方法亦称蒙特卡罗(Monte-Carlo)方法.因为通常的教科书几乎不涉及 此内容.了解的人不多。听到过的人又常把它看作是统计力学或核物理等学科的专门工具.很少想到这个方法与自己的科研工作有什么关系。 (Application of Monte Carlo simulation method of calculating the option price statistics, also known as Monte Carlo simulation method (Monte-Carlo) methods. Because textbooks are usually almost do not involve this content. Not many people understand. Heard of people often see it as a statistical mechanics or nuclear physics disciplines, such as specialized tools. Rarely thought about this method and their own research work has anything to do.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)
