此矩阵用高斯消元法求二元域矩阵H的逆矩阵，此算法不需要H时满秩矩阵，对于满秩矩阵，H的逆矩阵G为[P,I]，对于不满足矩阵，P的最后列为全零列，本算法适合刚进入编码领域的人，不知如何求生成矩阵，特别是当生成矩阵的为非满秩矩阵的时候可用。

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.

最小二乘法的一段程序，很好用，希望大家共享-The section of least squares procedures, very good, and hope that we share

您好组，我研究设计了ALU。这种ALU有块，模块，算法。 ALU是EXCUTE+， - ，x，：ALU....语言使用C ++。我认为这要紧的计算机系统。此外，ALU单元的背景为所有的系统进步。我希望这个ALU对大家都有利。ALU也需要IC设计产业。最好的问候
