A, the design requirements
1. The problem statement
Design program with ten medium realize sparse matrix with the table, multiply and transposed.
2. Demand analysis
(1) design the function up sparse matrix, the initial value.
(2) design function of sparse matrix output value.
(3) to construct the functions of the two sparse matrix addition, output final sparse matrix.
(4) to construct the functions of the two sparseness matrix multiplication, the output of the final sparse matrix.
(5) to construct the function of sparse matrix to buy, and output.
(6) exit system.
