采用Clewlow and Strickland 单要素日现货模型，利用Monte Carlo方法模拟商品现货价格的Matlab程序。-Commodity Model One Factor Spot Model：This code simulates commodity spot prices using the Clewlow and Strickland one factor daily spot model using a Monte Carlo approach. The derived stochastic differential equations (SDEs) are solved using several finite difference schemes.
