摘要
在期权定价公式的傅立叶变换积分公式中,运用留数定理将公式中的两个积分式子化简成一个被积函数衰减较快的积分函数式,从理论上提高了计算效率,缩短了计算时间,为投资者快速计算期权价值节约了时间.
In the integral formula of Fourier transforms of option pricing formula, by using residues theorem two integrations were simplified into a single numerical integration which has a faster rate of decay. In theory the simplification improved computational efficiency, shortened the computing time and saved time for investors to calculate option value.
