C ++中的线性方程组？ [英] System of linear equations in C++?

问题描述

我需要在我的程序中解决一个线性方程组。是否有一个简单的线性代数库的C ++，最好由不超过几个标题？我一直在寻找近一个小时，所有的那些我发现需要搞砸的Linux，编译DLL在MinGW等等（我使用Visual Studio 2008。）

解决方案

我认为Eigen是你要找的。

它是一个头文件库，并在许多编译器上编译。它甚至使用异国情调组装更快的数学。

这是显示线性求解器api的页面。

它有一些简单api的解算器。

I need to solve a system of linear equations in my program. Is there a simple linear algebra library for C++, preferably comprised of no more than a few headers? I've been looking for nearly an hour, and all the ones I found require messing around with Linux, compiling DLLs in MinGW, etc. etc. etc. (I'm using Visual Studio 2008.)

解决方案

I think Eigen is what you're looking for.

http://eigen.tuxfamily.org/index.php?title=Main_Page

It is a headers only library and compiles on many compilers. It even uses exotic assembly for faster math.

This is the page that shows off the linear solver api.

It has a few solvers with a simple api.
