What is the difference between dense and sparse matrices?
And when would I use which?
Dense matrices store every entry in the matrix. Sparse matrices only store the nonzero entries. Sparse matrices don't have a lot of extra features, and some algorithms may not work for them. You use them when you need to work with matrices that would be too big for the computer to handle them, but they are mostly zero, so they compress easily.
