一种基于矢量量化快速编码的图像压缩方法种基于矢量量化快速编码的图像压缩方法 (A Fast Vector Quantization Encoding Method for Image Compression)

本程序使用matlab语言,编制了一个基于通用似化学活度系数模型来计算四组分反应体系中各组分的汽液平衡状态的程序.(This procedure using the matlab language, developed a chemical based on a common activity coefficient model seems to calculate the four-component reaction system of the components of the vapor-liquid equilibrium of the program.)

基于离散余弦变换的一段音频水印嵌入程序，对毕业设计有一定的帮助(A discrete cosine transform-based audio watermark embedding program, designed for graduates of some help)

这里提供的电力系统潮流计算程序,其中的两个主程序名为lfnewton和decouple。程序由MATLAB语句编写而成，全部是源代码。(Here are the current procedures for a total of seven papers, two of the main program, called lfnewton and decouple. Written statement made by the MATLAB program, all the source code. MATLAB is a very good tool, should understand it. To read these two procedures will be able to judge the whole.)
