问题描述
在我编写的C ++应用程序中，我需要解决一个非线性方程组（N方程，N个未知数）。
In a C++ application I'm coding, I need to solve a system of non-linear equations (N equations, N unknowns).
我解决的系统会相当小（最多10个方程/未知数），因此性能不会是一个真正的问题。
我在网上搜索了一个非线性求解器库，我不能得到一个看起来很容易使用的东西（得到 NOX 和，但两者似乎都是我的需要的过分）。
The systems I'm solving will be rather small (up to 10 equations/unknowns), so performance is not going to be a real issue.I've searched the web a bit for a non-linear solver library, and I couldn't get to something which looks easy to use (got to NOX and C/C++ Minpack, but both seem to be an overkill for my need).
为此目的使用易于使用的库的任何想法和想法？
Any thoughts and ideas of easy-to-use libraries for this purpose?
推荐答案
你可以使用日s包，其中包括一个非线性求解器，用CI写。我发现唯一的问题是，你需要给它良好的初始估计。第二个选项是使用NLEQ或NLEQ2，我认为是优越的（在FORTRAN中的writtein，但很容易链接到C喜欢的语言，但我有一些问题找到它只是现在。有一个很好的网站，列出可能的选项at：
There are two options for you, you can use the sundials packages which includes a nonlinear solver, written in C I think. The only problem I've found with it is that you need to give it good initial estimates. The second option is to use NLEQ or NLEQ2 which I think are superior (writtein in FORTRAN but easy to link to C like langages. However I have had some problems locating it just now. There is a good web site with a list of possible options at: http://plato.asu.edu/sub/zero.html
