倒立双摆动matlab源代码，做倒立双摆动文章很少见，这个是原创，请朋友们提意见。(Inverted double swing matlab source code)

人脸识别中的光照处理方法，使用混沌与分形分析的例程，实现了图像的灰度化并进一步用于视频监视控。( Face Recognition light treatment method, Use Chaos and fractal analysis routines, Achieve a grayscale image and further control for video surveillance.)

IEEE14节点进行牛顿拉弗逊法计算电力系统潮流计算(IEEE14 node calculates Newtonian Raphson method for power flow calculation)

为给定的wav文件绘制频谱图（频谱照片）。内附程序及报告书。(Wav files for a given Spectrogram diagram drawing (spectrum photo). Included procedures and report.)

本程序是姚敏那本图像处理书中的赫夫曼定理的源代码，经验证无误。此文档是.m文件的形式，可以直接用matlab打开(This procedure is that the image processing Yao Min Huffman Theorem book source code, proven correct. This document is. M file form that can be opened directly with matlab)

当圆柱型阵列的来波方向为0.5137（对应的pi 坐标）时阵列波束形成方向图(When a cylindrical array for DOA 0.5137 (corresponding to the coordinates of pi) when the array beamforming pattern)

在轴箭头绘制坐标空间是很困难的，因为Matlab的内置函数图工程箭头坐标空间。这个函数的轴到图坐标计算及放置在正确的位置注释箭头。它还提供了一个按钮式功能重新同步线和箭头如果调整轴或人物，或变更线的属性。(Plotting an arrow in axis coordinate space can be difficult, since Matlab s built-in arrow function works in figure coordinate space. This function does the axis-to-figure coordinate calculation and places an annotation arrow in the correct location. It also provides a button-down function to re-sync the line and arrow if you resize the axis or figure, or change the line properties.)
