This C program computes the partition function of a model of random
copolymer at a selective interface using the transfer matrix approach
and various speed-ups (which can introduce some approximations -
negligible in the usual range of parameters). The code and some results
obtained with it are described in this paper (.pdf). Type ./zeta-copolymer -? for the list of options (and some help).
Here the C source. It is written in ANSI C and it has been tested under MacOSX and Linux.
