Dear David,
 
well I do not know what exactly you mean by modelling /simulation, but a  good
deal of what numerics people do (like integrating ODEs using Runge-Kutta  
schemes,
matrix calculations of all sorts) are implemented in the GNU Scientific  
library (GSL):
 
_http://www.gnu.org/software/gsl/_ (http://www.gnu.org/software/gsl/) 
 
Once you have that installed, there are Ruby bindings available for  it:
 
_http://rb-gsl.rubyforge.org/_ (http://rb-gsl.rubyforge.org/) 
 
There is extensive documentation available on those two webpages.
 
Best regards,
 
Axel
