igraph是一个建立和操纵无向图、有向图的开源C程序库，它既包含经典图论里的各种算法（例如最小支撑树、网络流等），也包含了最近的出现的一些网络分析算法（如社团结构搜索等）。igraph是C写的，这意味着你很容易在C/C++中使用它。如果你不熟悉这两种语言，或者觉得用C/C++太繁琐的话，igraph还提供了R语言（一种国外很流行的统计分析语言）和Python语言的接口，所以也很适合科研人员使用（我现在用的是Python，调用igraph很简单）。

共梯度算法程序代码.数学上，共梯度法实求解特定线性系统的数值解的方法，其中那些矩阵为对称和正定。共轭梯度法是一个迭代方法，所以它适用于稀疏矩阵系统，因为这些系统对于象乔莱斯基分解这样的直接方法太大了。这种系统在数值求解偏微分方程时相当常见。 共梯度法也可以用于求解无约束优化问题。 -Total gradient algorithm program code. Mathematics, the total gradient method for solving a particular linear system is the numerical solution methods, including those for the symmetric and positive definite matrix. Conjugate gradient method is an iterative method, it applies to sparse matrix systems, because these systems such as the Cholesky decomposition of the direct method is too high. Such systems in the numerical solution of partial differential equations are quite common when. Total gradient method can also be used for solving unconstrained optimization problems.
