OFELI is an object oriented library of C++ classes for development of finite element codes. Its main features are : * Various storage schemes of matrices (dense, sparse, skyline). * Direct methods of solution of linear systems of equations as well as various combinations of iterative solvers and preconditioners. * Shape functions of most "popular" finite elements * Element arrays of most popular problems (Heat Transfer, Fluid Flow, Solid Mechanics, Electromagnetics, ...).-OFELI is an object oriented library of C++ classes for development of finite element codes.

实现矩阵的LU分解，如果此矩阵可以实现LU 分解，就分解此矩阵，并输出分解后的L矩阵和U矩阵。此算法对于一些不能进行LU分解的矩阵，会给出不能进行LU分解的提示，对于进过一些基本的初等变化后可以进行LU 分解的矩阵，此算法也实现不了。

差分进化算法（DE）  由Storn和Price与1995年首次提出。算法起初是寻求解切比雪夫多项式拟合问题，由于该问题是一个实数拟合优化问题，因此两人采用实数编码直接表示个体，同时用向量差分来对向量群体进行扰动。据此提出的差分变异算子成为算法的主要的遗传操作。
