在模式识别中，样本的特征选取是很重要的，大大的影响识别率，样本的特征提取(In pattern recognition, feature selection of samples is very important, and greatly affect the recognition rate, sample extraction)

Write a MATLAB function lls_rd.m (rd stands for rank de… cient) to solve the LLS problem

说明：  statcom的simulink实现，采用dq解耦法控制。(STATCOM is built in Simulink, and DQ decoupling method is used to control.)

建模大赛城市表层土壤重金属污染分析试题图形与函数绘制(Modeling Contest heavy metal pollution of urban topsoil graphics and function draws questions)

基于matlab语音分析的分帧函数，可以实现对语音信号清音 浊音的分帧分析(Matlab speech analysis based on the sub-frame function, can realize the voiceless voiced speech signal analysis of the sub-frame)

用BFGS更新矩阵的信赖域法解优化问题的MATLAB程序(Trust Region Method For Solving Optimization Problem)

求解马尔科夫过程的一个过程，输入转移强度矩阵后，可以求得状态概率(A process of solving Markov process, the intensity of the input transfer matrix, we can obtain the state probability)

target tracking The CV and CA models can be used to model the distance between front and host vehicles, but we don’t know when a specific model should be used. The interacting multiple model (IMM) estimator [1] is an algorithm which can be used to handle such case. In IMM algorithm, at time k the previous estimates from the multiple models are mixed based on the mixing probabilities to generate different mixed initial conditions for different filters.

基于Matlab的带通滤波器的设计源码，可以通过此代码，模拟带通滤波器的设计。并附有仿真后的图像。(Matlab-based band-pass filter design source, through this code, analog band-pass filter design. Together with simulation, the image.)

This is a MATLAB program which is forms a power ssytem model and its controller. Its extremely useful.
