LEACHsim

这个Matlab程序用来仿真和分析六杆机构运动学，从而理解机构运动的原理。 (This program is my Dynamic machine project in mechanical engineering department of Amirkabir University of Technology. (www.aut.ac.ir) This program simulate and analyze the 6 bar mechanism indicated in HELP.pdf By running it: • you can see the simulation of mechanism motion • analysis figures)

96全国数模竞赛a题，使用matlab编程求解得到结果(96 national model competition a title)
