我在寻找一个.NET数学分析器，它使用的变量，运营商定制和用户定义的函数... 由于今天我用muParser（有一个包裹版本.NET），但我发现它太慢了！

I'm looking for a .NET Math Parser which uses variables, custom operators and user defined functions... Since today i've used muParser (there's a wrapped version for .NET), but i noticed it is too slow!

有谁知道另一种数学分析器（免费！）的作品pretty的好？

Does anybody knows another Math Parser (FREE!) that works pretty good?

我试图NCalc，但它不具有变量，所以它失败..

I tried NCalc, but it doesn't have variables, so it fails..

推荐答案

我发现这三个截至今日，所有这些都支持变量和用户定义的函数，但是的只有muParser似乎支持运营商定制：

I've found these three as of today, all of which support variables and user defined functions, but only muParser seems to support custom operators:

有关我的小玩具项目，我就跟着数学分析器.NET ，因为它支持 ^ 的权力，而NCalc不和muParser有点不吸引我一样多。还有另外一个好处：数学分析器.NET支持本地C＃委托定制的功能！ ，其他图书馆提供的解决方案别看优雅。

For my little toy project I went with Math Parser .NET since it supports ^ for powers whereas NCalc does not, and muParser somehow didn't appeal to me as much. There is another benefit: Math Parser .NET supports native C# delegates as custom functions! The solutions that the other libraries offer don't look that elegant.
