稀疏矩阵的操作(数据结构)(Operations of sparse matrices (data structures)) Operations on sparse matrices Requirement: 1. sparse matrices are represented by three tuples. 2., the same number of rows of sparse matrices A and B add matrix C, and find C. 3. for the A matrix transpose matrix D, output D. I happened to do it, too. Youre in luck! The following is written in C language, I wonder if it is feasible That the name of the matrix may not meet your requirements, you change it, ha ha. #includestdio.h The maximum value of 100 MAXSIZE / #define / * non zero element number Typedef struct triple { Int i, J; / * * / row and column.
