A coordinate list (coo) is a sparse matrix representation that stores only the non-zero elements of the matrix along with their corresponding row and column indices. This format is efficient for handling large matrices that contain a majority of zero values, as it reduces memory usage by focusing on the significant entries. The coordinate list enables quick access to matrix elements during operations like sparse matrix-vector multiplication, making it a vital tool in computational applications where efficiency is key.
congrats on reading the definition of coordinate list (coo). now let's actually learn it.
