For large sparsematrix, it is very important to keep the sparse of matrix in computation.
对于大稀疏矩阵,在计算中保持矩阵的稀疏性是很重要的。

Because the coefficient matrix of the equation to be solved is very sparse, the algorithm with the compact storage scheme is given and the computation cost is also reduced.
对于所求解方程的系数矩阵的高度稀疏性,给出了紧缩存储算法,节省了存储空间和减少了计算量。

Triple table is used to only store non-zero matrix elements to improve the program's efficiency of storage and computation because simulation model's Jacobian matrix is serious sparse.
