Yes. You can use MathLink, Mathematica's inter-application
communication protocol, to call Mathematica from within
your own programs or to call external programs from within

The Wolfram Research Web pages have more information about
Mathematica and MathLink, specifically:

I would also suggest that you look at Todd Gayley's MathLink 
Tutorial, available on MathSource, Wolfram Research's 
electronic library of Mathematica materials:

0206-693: A MathLink Tutorial

Todd Gayley

This tutorial supplements the material in the MathLink 
Reference Guide. It covers all aspects of MathLink 
programming, especially topics that are treated very 
briefly or not at all in the Reference Guide. Topics 
include: passing lists and arrays, error handling, 
using C++ and FORTRAN, graphics, packet types, 
troubleshooting, etc. This tutorial supersedes any 
other MathLink documentation by the author.

MathSource is accessible by email (mathsource at, 
by anonymous ftp/gopher ( and by 
World Wide Web (

I hope this helps.
