可以实现大规模的bfgs功能，进行目标函数的最优化求解，即L-BFGS-Can achieve large scale bfgs function, the objective function is the most optimal solution, ie, L-BFGS

这是一个L-BFGS的Matlab源代码

Net is defined over a data flow graph, which is derived from the iterative pro- cedures in Alternating Direction Method of Multipliers (ADMM) algorithm for optimizing a CS-based MRI model. In the training phase, all parameters of the net, e.g., im

有限记忆算法，用于处理大规模算法，算法原理为把不断迭代的牛顿矩阵分解并部分抵消达到减少运算量的目的(limit memory,for large-scale algorithms. The principle of the algorithm is to decompose and partially cancel the iterative Newton matrix in order to reduce the computational complexity.)
