牧场管理代码 应用于姜启源的数学建模(第三版)课后大作业(The Answer of the Assignment in the Book <MathModel>(Author:Jiang Qiyuan))

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

说明：  利用matlab编程求解瞬态问题，内容简单，利于入门(Using MATLAB programming to solve transient problems, the content is simple and easy to get started)

文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem. Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors. The models are used to design first, second etc. order predictors. The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The best prediction scheme obtains an average spectral distortion that is 0.46 dB less than for the reference method. )

In this we analyze the light out game with matlab.(Linear Algebra analyzing on Lights Out Game )

压缩感知里面的稀疏重建问题，在原来MP的算法的基础上，提出了分块的思想，即将原子库分块后，测试算法的性能。(Compressive sensing is refered as the block sparse algorithm is described,that is based on the original MP algorithm,and the atom libruary is divided into blocks ,and the performance is testified.)

matlab非线性kalman滤波工具箱，包括了ukf,pf等等，很好用(nonlinear kalman filter matlab toolbox, including ukf, pf, etc., very good)

i want code forr denoising

利用Matlab的GUI界面来进行倒立摆PID参数的设计(The design of PID parameter control of inverted pendulum using Matlab GUI )

说明：  使用交互式多模型技术，滤波器选择无迹卡尔曼滤波器。(We use ukf to achieve imm successfully)
