说明：  此程序中将两个离散时间信号卷积，在数字信号处理过程中很有用！(conversion)

美式期权计算程序，利用的是implicit euler方法进行计算(implicit euler method to calculate American option.)

Matching Pursuit 算法是信号分解的一种具体实现方法。但其本质上则是一种估计 信号模型参数的方法，因而可直接用于信号检测及参量估计。本文以谐波信号特征参量的估计为例，介绍了其具体实现方法。(Matching Pursuit algorithm is a specific method of signal decomposition. But by its very nature is an estimated signal model parameters, and thus can be directly used for signal detection and parameter estimation. In this paper the harmonic signal characteristics of the estimates of the parameters, for example, describes the specific implementation method.)
