供做算法研究人员参考，表示出两帧图像间各个像素点的相对情况，包括最后计算压缩图像的峰值信噪比和压缩效果的源码。( Algorithm for researchers to do reference, Between two images showing the relative circumstances of each pixel, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.)

本文主要介绍基于SIMULINK的SVPWM仿真，并且详细阐述了SVPWM 的算法。(This paper describes the SVPWM based on SIMULINK simulation, and detailed SVPWM algorithm.)

They are the programs of uniform quantization and non-uniform quantization. In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by a relatively small ("finite") set of ("values which can still take on continuous range") discrete symbols or integer values.

本论文首先阐述了利用Duffing振子进行微弱信号检测的基本方法及具体实现方法，论证了根据系统相轨迹的变化来判断目标信号中是否含有周期信号的混沌振子检测方法。将Lyapunov特性指数作为一种定量的混沌判别方法应用到微弱信号混沌检测领域，分别研究了连续系统和时间序列的Lyapunov指数计算方法。(his paper first discusses how to use the Duffing oscillator are the weak signal detection, the basic method and the realization methods, proved according to the change of the phase track system to judge whether a cycle of target signal of chaotic oscillator signal detection methods. Will Lyapunov characteristics as a quantitative index of chaotic identifying method applied to a weak signal detection field chaos, respectively, the continuous system and research of time sequence Lyapunov index calculation method. )

MATLAB基础教程，讲解了MATLAB基本运算和基本函数，以及基本绘图命令。(it is a MATLAB basic tutorial,including the basic arithmetic and functions, what s more, the basic drawing command.)

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

线搜索求简单单峰值函数的最小值程序设计，算法采用固定搜索方向方法。(Simple single-peak line search function to find the minimum programming )

Least-square curve fitting using polynomials is probably the most basic way to perform some parametric regression analysis. Foor basic tools for polynomial curve fitting are provided here. I also strongly recommend the exhaustive function POLYFITN

This provided rar file is a 100 best utility codes of MATLAB is useful in many purpose,,mainly used to sumarized d large data base...............
