说明：  本人收集的古扎拉蒂（Damodar N.Gujarai）《计量经济学基础》（中英文版）书籍及数据，还有《经济计量学精要》是学习计量经济学及金融分析的不二之选，配合matlab中新推出的计量经济学工具箱更是不错的选择(I collect Guzhaladi (Damodar N. Gujarai) &quot basic econometrics&quot (in English) of books and data, and &quot Essentials of Econometrics&quot is the study of econometrics and financial analysis, the best choice , with the new matlab toolbox of econometrics is a good choice)

kalman滤波的实现,是关于二维内的实现(the output of kalman filter)

介绍了matlab程序在信号处理中的应用和其中使用的程序(the introduction of matlab using in SP)

在matlab环境中，实现批量最小二乘算法(In the matlab environment, to achieve batch least squares algorithm)

一种经典的matlab齿轮损伤数据bp损伤识别，有齿轮故障数据(A classic matlab gear damage data bp damage identification, with gear failure data.)

说明：  算法是基于灰狼优化算法GWO优化VMD，可以大大提高VMD的分类准确率，提高优化时间。(This algorithm is based on GWO optimization VMD, which can greatly improve VMD classification accuracy and optimization time.)

简单的车牌定位程序 MATLAB环境下对简单的图片很容易定位车牌(license plates have three letters and four numbers,plate images were used in order to train the two neural networks,one for the letters and the other for the numbers)

The remarkable advance in hydraulic and electrohydraulic power systems resulted in producing control valves of very short settling time. The rapid closure of hydraulic transmission lines leads to severe pressure surge. Thattached Simulink file is developed to evaluate the applicability of oleo-pneumatic accumulators for the protection against this phenomenon. A lumped parameter model was developed for the transmission line, assuming four lumps, considering the effect of line resistance, inertia and capacitance.

图像处理的霍夫变换程序，采用M语言编写，对数字图像进行直线追踪(HOUGHLINES- detects lines in a binary image using common computer vision operation known as the Hough Transform. )

本代码用于实现图片中的光照补偿，效果较好，实用性较强！(The code used for illumination compensation in the picture, better practicality!)
