# AAE 568 Final Project - Optimal Collision Avoidance Maneuvers (CAM)
Spring 2024 AAE 568 final project working repo for an optimal low-thrust CAM.
## Usage
After cloning repo, simply add the scripts path and call the run_CAM.m or run_CAM_with_estimation.m script.
```matlab
>> addpath('scripts')
>> run_CAM
```
or
```matlab
>> addpath('scripts')
>> run_CAM
```
