灰色预测，可以对数据进行预测的程序。本程序为一阶模型。(Prediction, the data can be predictable procedures. This program is first-order model.)

image segmentation with fast support vector machine

This simulation demonsrtates the control of a dc motor using a speed control and current control loops.Typical dynamic responses od the dc motor are also shown. The motor is initially at standstill and at no load when a step command in speed is applied when steady-state conditions are reached, a reversal of speed is commanded followed by a step load application.

PSO算法简单、易实现且参数较少，现已被应用于函数优化、神经网络训练、模糊系统控制以及其它遗传算法的应用领域(PSO algorithm is simple, easy to implement and less parameters, have been applied to function optimization, neural network training, fuzzy system control and other applications of genetic algorithms)

This is code demo for recognition hand-finger using matlab

【债券回购量化投资模型】：本人在投资公司做量化投资的，分享一个简单的债券回购量化投资模型，在rar压缩文件附有数据，模型的原理与策略系历史最大开盘价合约进场，细节不多讲，做量化投资的朋友可以了解一下。([Bond repurchase quantitative investment model]: I do quantitative investment in investment companies, sharing a simple bond repurchase quantitative investment model, rar compressed files with data, principles and strategy of the largest in the history of opening contract model approach , not much talk about the details, do the quantitative investment friends can look at.)
