一个matlab程序可以调入和应用3D Max (.3ds)和Autocad (.dxf)文件。能够利用OpenGL作显示并进行简单的操纵（旋转，平易，重叠等）(a Matlab procedures can be transferred and applied 3D Max (.3 ds) and Autocad (. dxf) documents. To use OpenGL for show and simple manipulation (rotate kind, overlap, etc.))

英国谢菲尔德大学推出的GA算法工具箱，只能说，很好，很强大(GA toolbox by Sheffield Univ, excellent and perfect.)

In mathematics, the Fibonacci sequence is the following infinite sequence of natural numbers: The first element is 0, the second is 1 and each remaining element is the sum of the previous two: Each element of this sequence is called Fibonacci number. This sequence was described in Europe by Leonardo of Pisa, XIII century Italian mathematician known as Fibonacci. It has numerous applications in computer science, mathematics and game theory.
