断层正演的matlab小程序，用于模拟不同断距的断层地震反射特征，可以用于地震断层分辨率研究(seismic Fault forward for matlab，，seismic Fault forward for matlab seismic Fault forward for matlab)

74161实习十进制计数功能，有预置端和清零端(Decimal count )

指纹识别源代码。思路完全是按照文件夹中网页里介绍的方法，即提取指纹中的分叉点和端点的位置作为指纹的特征值。由于今天太忙，对图像的预处理作的很失败，程序会提取出很多伪点，而指纹轮廓也没有想出办法过滤。汗，你看看能不能参考把。 三个m文件，fd.m提取指纹中的分叉点，fd2.m提取指纹中的端点，Cpoint.m则是前两个文件运行中需要调用的掩模函数。(fingerprint identification code. Thinking is entirely in accordance with the folder on the website Lane, that the fingerprints of the bifurcation point and endpoint position as a fingerprint eigenvalues. As today are too busy, the image preprocessing for the failure, the program will extract a lot of pseudo-point, and the fingerprint profile nor find a way to filter. Khan, you can look at the information put. 3 m documents, fingerprints fd.m the bifurcation point, fd2.m fingerprints of endpoint, Cpoint.m are two documents before the operation need to call the mask function.)

The M-files that are in the folders "Operations," "Extension Principle," and "Plotting" are all keyed into a specific chapter of the book Uncertain Rule-Based Fuzzy Logic Systems: Introduction and New Directions, by Jerry M. Mendel, and published by Prentice-Hall, 2000. There are also some miscellaneous M-files.

LMD matlab 程序 局域均值分解，利用滑动平均求的，不是用三次样条(LMD matlab program local mean decomposition, using the sliding average demand, not by Cubic Spline)

求星图中星象坐标的matlab函数，输入星图，利用交叉投影方法得到星象所在区域的四个顶点坐标和星象的质心，能够快速的求得星图星象的位置信息(Astrology chart for stars matlab function of the coordinates, enter the star maps, cross-projection method using astrology region and the four vertex coordinates of the mass center of astrology, the Express can find the location of star maps astrology information)

matlab的画图的程序使用，数形结合的重要工具，灵活掌握对于matlab开始的学习很重要。(matlab program to use the Paint, The Combination of the important tools, flexibility of learning for matlab start is important.)
