把matlab计算后的数据保存成obj格式的文件，能保存点和点点之间的连接关系，即obj格式的中的v和f-Obj format to save data into files that can save the points and little connection between the relationship that the v in obj format and f

可以读取obj格式的文件到matlab空间中，obj格式的文件中，只能包含点和面的信息-Obj file format can be read into matlab space, obj file format, can contain only the information points and surfaces

matlab读取和显示obj格式的三维模型文件，经验证效果很好。-Matlab to read and display the 3D model file in obj format, and proved the effect is very good.
