Image-Segmentatin-and-Thresholding-Method

matlab code to demonstrate jpeg compression algorithm.

地理坐标系转地磁坐标系，输出磁地方时等参量(Geographic coordinates turn geomagnetic coordinate system, the output magnetic local time and other parameters)

数据互联算法。绘制出了目标真是轨迹、测量轨迹、PDAF估计轨迹和NNSF估计轨迹，并进行了对比分析。(Data Association Algorithm. Drawn out of the goal really track the trajectory measurements, PDAF estimated trajectory and NNSF estimated trajectory, and a comparative analysis.)

基于光伏模块直流物理模型 在 matlab 仿真环境下 开发了光伏阵列通用仿真模型 利用该 模型 可以模拟任意太阳辐射强度 环境温度 光伏模块参数 光伏阵列串并联方式组合下的光伏阵列 I-V 特性 此外 该模型还融合了光伏阵列的最大功率跟踪 MPPT 功能 可以用于光伏发电系统和风光复合发电系统的动态仿真(PV module DC physical model in matlab simulation environment developed photovoltaic array generic simulation model using the model can simulate the IV characteristics of the PV array at any ambient temperature solar radiation intensity photovoltaic array photovoltaic module parameters of series and parallel combinations based on the model also incorporates the addition The maximum power of the PV array can be used to track the MPPT function dynamic simulation of photovoltaic systems and wind hybrid power system)

在群体进化若干代后,将弱解空间删除,在以后的进化进程中以同样的群体大小只在强解空间进行群体的繁殖,则可加大强解空间的个体密度,提高解的精度,这样有助于性能优良的个体的产生,(After several generations of evolution in the population, a weak solution space removed in the future evolution of the process with the same population size in a strong solution space only breeding colony, it can increase the density of strong individual solution space, to improve the accuracy of the solution, This helps produce good performance of individuals,)

在本演示中，一个简单的图像检索方法，提出基于图像的颜色分布。用户只需提供一个“例子”的形象和搜索是基于这个例子（例如基于查询的图像）。包括图像和教学指令!!!(In this demo, a simple image retrieval method is presented, based on the color distribution of the images. The user simply provides an "example" image and the search is based upon that example (query by image example). Experiment image and instruction included!!!)

Circuit Analysis II with MATLAB applications

matlab的gcv函数，可以用于求取正则化参数。是regtools工具箱中的(The gcv matlab function that can be used to strike the regularization parameter. Is regtools Toolbox)

说明：  教你如何使用编写matlab中的S-Function(Teach you how to use matlab in the preparation of the S-Function)

说明：  采用FDTD计算2维光子晶体的散射和透射的可执行程序小软件(Calculated using FDTD 2-D photonic crystal scattering and transmission of the executable program small software)
