Weird NullReferenceException in third party dll: C#

问题 I have a strange error, which has started suddenly and which is driving me crazy. In my C# application, I am doing some heavy mathematical calculations and for that purpose, I am using CenterSpace's NMath library. Recently, when I started my application from inside Visual Studio 2015 in order to debug it, the application started to crash because of NullReferenceExceptions in NMath.dll, whenever I call an NMath library method (and another library which we have written, as well). In order to

The speed of .NET in numerical computing

问题 In my experience, .NET is 2 to 3 times slower than native code. (I implemented L-BFGS for multivariate optimization). I have traced the ads on stackoverflow to http://www.centerspace.net/products/ the speed is really amazing, the speed is close to native code. How can they do that? They said that: Q. Is NMath "pure" .NET? A. The answer depends somewhat on your definition of "pure .NET". NMath is written in C#, plus a small Managed C++ layer. For better performance of basic linear algebra

For better performance of basic linear algebra operations, however, NMath does rely on the native Intel Math Kernel Library (included with NMath). But

C# linear algebra library

Is there stable linear algebra (more specifically, vectors, matrices, multidimensional arrays and basic operations on them) library for C#? Search yielded a few open source libraries which are either not updated for couple of years or are in an early beta stage - and Centerspace NMath. Which alternatives are worth checking? Rinat Abdullin Math.NET . We're using it in production. See: http://en.wikipedia.org/wiki/List_of_numerical_libraries http://www.alglib.net/ - Open source.
