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

Chain of packets in MathLink: are the packets always strictly ordered?

The Documentation does not state clear the order of packets returned by slave kernel via MathLink. It is natural to suppose that (when sending an input expression with head EnterExpressionPacket and working in standard mode): 1) the last packet…

Computing derivatives in Mathematica/Mathlink

I'm trying to figure out how to use Mathematica from C via Mathlink. If I just want to compute the value of a built-in function, I can do MLPutFunction( lp, "RiemannSiegelZ", 1L); MLPutDouble(lp, val); and all is fine. Now, if I…
