说明：  灰色理论的应用，是一种成语实现，用于预测数据。(Application of Grey theory is a kind of idiom to achieve, to predict the data.)

一种智能优化算法-人工神经网络算法的matlab源程序(artificial neural network)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，基于线性预测系数(LPC)的语音信号重构。给出了完整的LPC matlab程序，包括语音信号采集，LP预测系数，阶数的选择以及预测结果误差曲线。（很好用）(This version of the program and then on the successful commissioning matlab2012b information previously graduation when found online, we want to be useful, based on linear prediction coefficient (LPC) voice signal reconstruction. Given a complete LPC matlab procedures, including voice signal acquisition, LP prediction coefficients, select the order and the prediction error curve. (Well used))

matlab下实现降噪，功率谱计算。％程序中设定采样点数为256个，采样频率为10000hz， ％输入信号为随机噪声和两个正弦的合成信号 ％设定的滤波器的截止频率为3500hz ％通过挈比雪肤滤波器，运行程序，比较滤波前后的频域波形 ％滤波去除了高频信号(matlab achieve noise reduction, power spectrum calculation. Sampling procedure set for 256 points, the sampling frequency of 10000hz, input signal for the random noise and the two sinusoidal signals synthetic filter set a cut-off frequency 3500hz manner than through the filter雪肤, run procedures, compared before and after filtering in frequency domain waveforms filtering in addition to high-frequency signals)

说明：  matlab编写的bp神经网络程序，适合初学者学习，内部注释清楚(matlab prepared bp neural network program, suitable for beginners to learn the internal comments clear)

通过文件读写方式实现Matlab和Modelsim的联合仿真(Be achieved through the document literacy co-simulation Matlab and Modelsim)

根据韩京清先生提出的自抗扰理论，用matlab/simulink实现自抗扰的状态观测器，并进行模块封装。便于同学交流学习(the simulation of ESO based on matlab/simulink is covered into a block.)
