这是一个有关PI模型系统辨识的MATLAB程序，并附有MATLAB仿真30个案例以便于学习(This is a PI model identification program)

This function produces an image of a 3D object defined by matrix a(l,m,n) in terms of voxels the image is a view after rotating the object by angles alfa and beta (in degree) b is the image and d is its ditance to the viewer matrix The first figure depicts the object using only its gray level values The second image depicts the object using some lighting effect rotate3d may be used for reorientation but the obtained image is planner
