输入滤波器说要参数，包括带宽，活波损耗，通带波纹计算平行耦合线滤波器阻抗(Calculate the parallel coupled line filter impedance)

光伏微网中超级电容之间的均压电路仿真模型。(PV microgrid super capacitor between the equalizing circuit simulation model.)

基于matlab计算洛伦兹-朱德模型的matlab源代码，只需运行程序代码选择金属名称和模型类型即可自动输出不同频率下的介电常数值，非常方便(Based on the calculation of the Lorentz matlab- Zhu model matlab source code, simply run the program code to select the name and model type of metal can be automatically output dielectric constant values ​ ​ for different frequencies, very convenient)

Create a table for managing procurement for many people.

A code to fit a curve on sampled data using moving least squares method. MLSM is generalized form of weighted least squares and firstly introduced to use in meshless Finite Element Method (FEM). The main feature of this method is that the weight function is updated from point to point which enables the user to control “closeness of fit”.This code is performed for 1D fitting and is tested on a sinusoid function.
