对原始图像与gabor小波进行卷积后，得到gabor幅度图，对其进行灰度值分析和二值化后就能得到人眼窗口的定位(The original image after convolution with gabor wavelet get gabor magnitude diagram, its gray value analysis and binarization can get after the positioning of the eye window)

用HOMER软件画出的某地区一年每小时的光照，将其导出为文本格式，可导入到MATLAB中供研究人员使用(HOMER software to draw an area with a light year per hour, export it to a text format that can be imported into MATLAB for researchers)

三相PWM整流器逆变器 实现单位功率因数的逆变(three phase inverter)

本压缩包提供了本人课程教学期间课堂演示的PCM编码与解码、2FSK、2ASK、2PSK调制、基带升弦系统。每个模块达到参数都作了优化，以求获得良好的演示效果，对于学习通信原理课程、本科课程或毕业设计同学非常有用。(The folder include the code for PCM ,2ASK,2PSK,2FSK, base-band raised cosine System. All this was did in the matlab7.0/simulink 。 the parameters in every module prefer in order to get the excellent result .the folder is very useful for students in learning the communication theory and simulink .especially for lesson tasks .)

针对二维矩形条带装箱问题提出了一种启发式布局算法，即底部左齐择优匹配算法（lowest—level left align bestfit，简称LLABF）．LLABF算法遵循最佳匹配优先原则，该原则综合考虑完全匹配优先、宽度匹配优先、高度匹配优先、组合宽度匹配优先及可装入优先等启发式规则．与BL（bottom-left），IBL（improved-bottom-left）与BLF（bottom—left-fill）等启发算法不同的是，LLABF能够在矩形装入过程中自动选择与可装区域匹配的下一个待装矩形．计算结果表明，LLABF结合遗传算法（genetie algorithm,简称GA）解决二维条带装箱问题更加有效．(A heuristic placement algorithm for two-dimensional rectangular strip packing problem is proposed, which is called bottom-level left align best fit algorithm (LLABF). Different from BL (bottom-left), IBL (improved-bottom-left) and BLF (bottom-left-fill) heuristic algorithms, LLABF can automatically select the next rectangle to be loaded that matches the mountable region during the rectangular loading process. Genetie algorithm (GA) is more effective to solve the two-dimensional strip packing problem.)
