Questions tagged [mathlink]

MathLink is an API provided by Wolfram that allows programs to expose functionality to Mathematica and/or utilize the power of Mathematica's kernel.

"Extensively used within the Mathematica system itself, MathLink is Mathematica's unique high-level symbolic interface standard for interprogram communication. With convenient bindings for a variety of languages, MathLink immediately allows arbitrary symbolic objects—representing data, programs, or any other construct—to be efficiently exchanged between programs, on one computer or across a heterogeneous network." - MathLink API

CheckAbort inside MathLink functions?

I just found that such MathLink functions as LinkWrite and LinkRead have something like its own internal CheckAbort that absorbs any aborts, and does not propagate them further. This can be easily shown with LinkRead: link =…

Understanding Kernel-FrontEnd communication -- Why does my Front End freeze?

EDIT: Just a confirmation whether you can reproduce this or not would be useful. Only a single computer is needed to try this (no remote connection necessary). Update It seems other can't reproduce this on Mac or Win7, so it's either WinXP-specific…

How to make external Mathematica functions interruptible?

I had an earlier question about integrating Mathematica with functions written in C++. This is a follow-up question: If the computation takes too long I'd like to be able to abort it using Evaluation > Abort Evaluation. Which of the technologies…

Possible to use Mathematica from other programming languages (python/C#)?

Is it possible to use Mathematica's computing capabilities from other languages? I need to do some complex operations (not necessarily symbolic, btw), and it'd be pretty sweet to be able to just call Mathematica's functions or running Mathematica's…

Incorrect $SystemID in Mathematica

I am trying to link Mathlink libraries in mathematica. I am using a x86_64-suse-linux OS, but when I check $SystemID in Mathematica, it tells me I am using 'Linux' instead of 'Linux-x86-64'. This is a problem because if I try to link the library as…
