说明：  2机5节点电力系统潮流计算算例，可以作为学习潮流计算的案例(The power flow calculation example of 2-machine 5-bus power system can be used as a case of learning power flow calculation)

本程序是用MATLAB编写的孤立词的语音识别的程序，包含mel倒谱分析以及单个词的语音识别。(This procedure is used to prepare MATLAB isolated word speech recognition procedures, including mel cepstrum analysis, and single-word speech recognition. )

仿照着《小波去噪中软硬阈值的一种改良折衷法》一文写的程序，对比了软、硬以及软硬阈值折衷法的信噪比及均方根误差。仿真出来之后，原信号的信噪比是负的，不知道为什么？均方根误差的值也比较大，不知何解？信噪比和均方根误差是参照《基于matlab的小波去噪仿真》：吴伟，《信息与电子工程》 一文写的(Modeled on the written procedures of the hard and soft threshold wavelet de-noising an improved compromise " , compared to the soft and hard compromise between the hard and soft threshold signal-to-noise ratio and root mean square error. Out of the simulation, the signal-to-noise ratio of the original signal is negative, do not know why? The value of the root mean square error is relatively large, do not know why? Signal-to-noise ratio and root mean square error with reference to the wavelet denoising matlab-based simulation: Wu Wei, " Information and Electronic Engineering" written)

基于DCT变换的图像压缩的基本原理及其实现步骤。采用DCT变换压缩的依据。图像压缩过程的最后步骤是编码量化了的图像。在此,我采用的是Huffman编码方法。并使用MATLAB7.0实现DCT图像压缩的仿真。(DCT based on the image compression)

根据系统的动力学方程m文件和simulink求出系统的平衡点(Based on the system dynamics equation of m documents and simulink the equilibrium point of system)

说明：  分变模态分解（Variational Mode Decomposition，VMD）是一种具有坚实数学基础的分解算法，能够通过建立约束变分模型表达式，将信号以非递归的方式自适应地分解为若干本征模态分量(Variational Mode Decomposition is a decomposition algorithm with solid mathematical foundation. It can adaptively decompose signals into eigenmodes in a non-recursive manner by establishing constrained variational model expressions.)

说明：  程序描述了电压为-0.377V的情况下，卡尔曼滤波器的输出。其中“+”为观测值。程序注解写的很清楚很容易看懂。(Procedure describes the voltage of-0.377V, the Kalman filter output. Which+ For the observed values. Notes written procedure is easy to understand very clearly.)
