这是GMSD算法的matlab程序，描述了在图像去噪方法的作用(This is GMSD algorithm matlab program, describes the role of image de-noising method)

说明：  针对智能微电网优化配置问题，分别对微电网中风机、光伏和储能电池进行容量设计，并采用粒子群算法对系统进行优化配置。(Aiming at the optimization configuration of the smart microgrid, the capacity design of the wind turbine, photovoltaic and energy storage batteries in the microgrid are respectively carried out, and the particle swarm algorithm is used to optimize the configuration of the system.)

说明：  根据设计指标提取广义切比雪夫滤波器阶数和传输零点位置，参照《新型微波滤波器的理论与设计》_褚庆昕一书，并提供了滤波器耦合矩阵的计算程序，参照Richard Cameron的方法。(The order of the generalized Chebyshev filter and the position of the transmission zero point are extracted according to the design indicators. Refer to the book "Theory and Design of New Microwave Filters" _ Chu Qingxin, and provide a calculation program for the filter coupling matrix.)

说明：  基于基本牛顿法求极值点需注意： 初值点要接近极值点，否则不收敛 (Newton s Method function extremum)

this is matlab code for estimating the static linear system(system function is time variable) with Recursive Least Squre and 2 solutions for better result. 1- using the Covariance Matrix Reseting in a specefic time. 2-using the RLS with Forget Factor this program is written by matlab 7.0. Here we want to estimate the below function: 1-u^2+(1+tansig(0.1*(t-375)))*u^3+u^5+3*u^7 finally,there are plots for showing results.

Useful for feature extraction in image processing
