欧式股票期权的显式差分定价法,通过输入股票期权的波动率、贴现率、标的资产的定价等相关数据，计算出股票期权的理论价格(the explicit differential pricing method in European stock options )

This program is to plot 3-D radiation pattern of 2-element array antenna.

维纳滤波器，可以实现fir滤波和wiener滤波显示滤波结果(wiener filter)

Fuzzy knowledge-based system identification and modeling process is composed of two parts: variable identification and parameter identification. In variable identification, the significant variables of the system are identified among the set of possible variables. In parameter identification, the parameters of the knowledge-based system that describe the relationship between input and the output variables are identified. Parameter identification method consist of two steps: 1-find fuzzy clusters to establish the number of fuzzy rules 2-optimize the rule consequents. This code perform a fuzzy clustering using subtractive clustering
