Description: . In accordance with the concept of compressed storage, only the sparse matrix storage of non-zero element to the two triples (i, j, e) to indicate the non-zero matrix element of the rows, columns and numerical, on the identification of a non-zero element. Thus, sparse matrix can be expressed non-zero element of the ternary array and determine the ranks of a few. 2. User input data as triples of rows, columns and the number of non-zero element, separated by commas. And enter the non-zero element of the rows, columns and numerical. 3. This procedure only for two four matrix computation, the results matrix should be another generation, with two-dimensional array of storage and placed in a new matrix
