optical character recognition is used to convert images of any paper into soft copies

This is the Newton Raphson program for power system

本文介绍了一种将Matlab编译成可执行程序的一种方法，它使得Matlab编写的程序能够完全脱离Matlab这个环境来执行，从而大大提高了程序的应用范围和使用价值(This paper presents a Matlab will compile into an executable, It makes Matlab prepared by the procedures to be immune from the Matlab environment to implement, thus greatly improving the procedures and scope of the application of value)

选取windows系统自带的ding.wav信号作为分析对象，在Matlab软件平台下，利用函数wavread对音频信号进行采样，记住采样频率和采样点数，听一下原始声音sound(y, fs, bits)。 （2）音频信号的频谱分析，先画出音频信号的时域波形；然后对音频号进行快速傅里叶变换fft(y,N)，N取32768，画出信号的频谱特性，加深对频谱特性的理解。 （3）根据频谱，反演时域特性，画出时域波形。寻找幅值最大的两个频率，此频率除以fft点数在乘以采样频率就是信号的主频，即可合成信号的时域图形，听一下声音。 （4）对原音频信号进行1024点的分段付立业分析meshgrid （5）根据主要频线合成音频，并画出时域图形，试听合成效果。 （6）采用线性插值（linspace）和傅立业反变换(fliplr, ifft)分别合成音频，并画出时域图形，试听效果。 (err)

多相合成：将多个窄带信号合称为一路宽带信号，合成后的信号频率无相互干扰(The multi-phase synthesis: multiple narrowband signals collectively known as the way broadband signals, the synthesized signal frequency interfere with each other)

matlab 画图 三维 函数 等高线，等值线(matlab drawing a three-dimensional function contours, contours)

Motion-Compensated Frame Interpolation (MCFI) is a technique used extensively for increasing the temporal frequency of a video sequence. In order to obtain a high quality interpolation, the motion field between frames must be wellestimated. However, many current techniques for determining the motion are prone to errors in occlusion regions, as well as regions with repetitive structure
