此Matlab代码实现了Drude-Lorentz和Debye-Lorentz算法(LD模型)，用于计算金属的介电常数。当然Drude-Lorentz方法也可以用来计算纯水的。-This Matlab code implements the Drude-Lorentz and Debye-Lorentz algorithm (LD model), used to calculate the dielectric constant of

采用DRUDE模型，对多种金属（或者纯水）的介电常数进行数值计算。-By DRUDE model, a variety of metal (or water) in the numerical calculation of the dielectric constant.

利用Drude-Lorentz 模型设定金属的介电常数和利用Debye-Lorentz设定纯水的介电常数-Drude-Lorentz model for the dielectric constant of metals and Debye-Lorentz model for the dielectric constant of pure water

给定水的温度和频率，自动计算纯水的复介电常数。(Calculate the complex permittivity of pure water.)
