说明：  稀疏矩阵算法及其程序实现（杨绍祺）。本书较全面的介绍了在求解非线性代数方程组，非线性微分方程组和非线性优化等问题时所产生的稀疏线性化代数方程组的稀疏矩阵算法。
(Sparse matrix algorithm and program implementation (Yang Shaoqi). More comprehensive introduction to the book in solving nonlinear algebraic equations, nonlinear differential equations and nonlinear optimization problems arising from the sparse linear algebraic equations sparse matrix algorithm.)
