Did someone already made a Pointplot3d for a Principal Components Analysis with projections for some data points on the eigenvectors?
I like this example very much:

but I want to add projections on the three eigenvectors for some data points. I think it has to do something with the dot product, but I do not know how to do it in Maple.
Hopefully someone already did this and is willing to share it.
kind regards,
Harry
