MATLAB does not have any built-in functions specifically for clustering lines. However, you could achieve the goal of clustering lines following these two steps:
1. Define the distance between the lines. There are many ways of defining this and you should choose the most appropriate one based on the objective of your application. Just as an example, you can choose Hausdorff distance.
2. Based on the distances you calculated in step 1, run any clustering method to cluster the lines. For example, you can use kmeans.
