Vehicom LTE Link Level Simulator (The LTE link level simulator is a comprehensive simulation software used for algorithm development, performance evaluation and system validation associated with LTE systems. The simulator have Matlab and C versions. The C version simulator consists of optimized algorithms which can be easily transferred to DSP platform. All the functional blocks provide dynamic memory allocation for data blocks and easy settings of parameters offering advanced user flexibility to customized simulation. When compared to other LTE simulation tools such as Steepest Ascent LTE toolbox and IsWireless LTE PHY Lab, our software not only provides a friendly GUI with various settings, user defined input and output data, and open architecture to integrate user defined function blocks, but also integrates our proprietary high-speed channel models for vehicle applications and high-speed trains applications. The The key features of the LTE link level simulator are summarized as below: 1) fast simulation speed, 2) )

包括牛顿法，拉格朗日法，ＬＵ分解法，１００*１００阶稀疏矩阵方程组的解法等(Including the Newton method, Lagrangian method, LU decomposition method, 100* 100 band sparse matrix equations of the solution, etc.)

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.)
