它要求用户提供一系列的静态图像,称为艺术家对象。这些图像可以是通过Matplotlib创建的任何类型的可视化对象,例如Figure、Axes、Line2D等。用户需要将这些静态图像存储在一个列表中,然后通过ArtistAnimation来显示这些图像的序列。ArtistAnimation会按照用户指定的时间间隔逐帧地显示这些图像,从而实现动画效果。这种方法适用于已经...

which has created, in a single line, a list of rotation matrices. Vectorization also applies to the operators, for instance >>>A=R*SO3.Ry(0.5)>>>len(R)32 will produce a result where each element is the product of each element of the left-hand side with the right-hand side, ie.R...
