How can I store the feature descriptors for all 3D points found in Structure from Motion?

I am running the example on Structure from Motion from MathWorks. I have managed to find 3D points from my 2D images, but I also need to store feature descriptors for each 3D point, so that I can perform 3D-2D matching later on. How do I go about this? I can save the features for each image separately, but I don't know how to later match them to each 3D point.
