Recall from Section 3.4.2 that a matrix is said to be sparse if most of its entries are zero. More formally, assume a m x n matrix A has sparsity coefficient (A)

< < 1, where y(A) = d(A)/s(A), where d(A) is the number

of nonzero elements in A, and s(A) is the size of A

formally, assume a m x n matrix A has sparsity coefficient (A) < < 1, where y(A) = d(A)/s(A), where d(A) is the number of nonzero elements in A, and s(A) is the size of A (in this case, s(A) = mn).
