This model was inspired by the classic paper "Galactic Bridges and Tails" (Toomre & Toomre 1972). The original paper explained how disc shaped galaxies could develop spiral arms. Two disc shape galaxies originally are far apart. They then fly by each other and almost collide. Once the galaxies are close enough, mutual gravitational forces cause spiral arms to form.

此示例说明如何将扩展 Kalman 滤波器与 Simulink® 中的 MATLAB® Function 模块结合使用，以根据雷达测量值估计飞机的位置。滤波器实现在 MATLAB Function 模块中进行，其内容存储在 Simulink 模型本身中。
