此程序用于在GUI界面下计算光流，对于研究流的学者有重要参考价值..(this code demenstrates the computation of optical flow.)

Heritrix官方开发文档，crawler.archive.org/articles，提供了基本的类的开发介绍。((Heritrix official development documents, crawler.archive.org/articles, provides a basic introduction class development.))

求点d1到直线d2-d3的距离，并画线。范例： [d dl]=find_dl([2 1],[8 3],[4 7]) 则 dl=[6 5]。(Example: [d dl] = find_dl ([2 1], [8 3], [4 7]) if dl = [6 5].)

说明：  配合使用可以实现基于循环平稳信号的盲源分离。使用JADE和SOBI算法。自己编的(BSS based on cyclostationarity)

自己编写的模拟退火粒子群算法，里面含有测试函数，比较简单，适合初学者。(I have written simulated annealing particle swarm algorithm, which contains a test function is relatively simple, suitable for beginners.)

遗传算法中交叉算子的MATLAB程序 (Genetic algorithm crossover operator of the MATLAB program)

A generalized Richardson extrapolation routine that can perform multiple extrapolation steps, can accommodate arbitrary leading error terms, can handle any uniform refinement scheme (e.g. h/2, h/3, h/5, etc), and can report a full extrapolation table including comparing against a known good solution. Able to handle vector inputs. Compatible both with MATLAB and Octave. Includes Octave-style unit tests.
