kalman程序，用matlab编写！里面有kalman滤波程序介绍！(kalman procedures prepared by matlab! There are kalman filtering process introduced!)

说明：  用matlab语言写的EM(Expectation maximization)算法,用于模式分类(Matlab language used to write the EM (Expectation maximization) algorithm for pattern classification)

ecma-368 ultra wide band ber test5

太阳电池组件生产厂家通常仅为用户提供产品在标准测试条件(STC)下测出的Isc、Voc、Im、Vm、Pm值,本程序根据这些仅有的工厂测试数据在工程精度下复现光伏电池或之阵列在不同日射、不同温度下的I—V特性。(Solar module manufacturers generally only provide users with products under standard test conditions (STC) measured Isc, Voc, Im, Vm, Pm value, this program is just a plant based on these test data reproduced in the engineering precision PV battery or the array of different insolation, I-V characteristics at different temperatures.)

用matlab编写的SQP优化函数。可以求解目标函数和约束函数（等式和不等式）都为非线性的优化问题。(SQP solving function)

DVR SIMULATION ON MATLAB VERY USEFUL

粒子滤波，用来实现目标跟踪,多目标跟踪，及目标跟踪及定位等,解决非线性问题的能力比卡尔曼滤波,EKF,UKF好多了,(Particle filter, used to achieve target tracking, multiple target tracking and target tracking and positioning, the ability to solve nonlinear problems Bikaerman filtering, EKF, UKF much better,)

UWB，超宽带信号分析必用的子函数，第9部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 9!)

采用matlab编写的复化梯形公式求解方程(Trapezoid formula and solve complex equations)

遍历文件夹下的文件，并计算类内距离和类间距离。(Traverse folder under the file, and calculate the distance between the within-class distance and class.)
