中文摘要:提出了一种求解带有跳跃的双障碍期权定价模型的数值方法.算法采用了Crank-Nicolson有限差分格式和复化梯形公式对模型进行离散,对离散后的线性系统采用GMRES迭代法求解,并且构造了一个新的预处理算子以加速迭代法的收敛.数值实验验证了该方法能快速求解模型并达到二阶收敛精度. |

Numerical Solutions for Pricing Double Barrier Options under Jump-diffusion |
|
|
Abstract:A numerical method was proposed for double barrier options under jump-diffusion. Crank-Nicolson scheme and composite trapezoid formula were applied to discretize the pricing model. The resulting linear system was solved by GMRES with a preconditioner. Numercial experiments show this algorithm can fastly obtain solutions and reach second order convergence accuracy. |
