Why do we store cumulative # entries instead of just # entries? I know we can easily go from one to another, but it seems like the unintuitive way to store the cumulative # entries. Is there a reason we would want this value?

Are array of linked lists and compressed column format easy to do matrix operations? I do not see that they are easy. Can you give some examples?

Is the conversion to a sparse matrix relatively simple/fast? I feel like constantly having to convert in between the two forms may be a lot of wasted time/space.

I am a little bit confused why we don't use vector in C++

Can we turn associative array into a hash map to increase its efficiency?

Why compressed column format gives fast matrix operations?

Do we ever use some "density threshold" to convert from this sparse format to a dense one if a mesh gets sufficiently fine?

What's the industry standard for storing sparse matrixes?
