Hi Chris.

(switched to gnucap-devel, please subscribe if you havent already)

this sounds familiar. I don't know of a way to get the matrix with
gnucap. there are some hacks in gnucap-uf though. i've got three
scenarios where i'd like to access the matrix
- one is just debugging. in gnucap-uf some simulations have a 'dm' (dump
  matrix) switch.  this triggers a matrix printout somewhere near
- another one is a remote control for external programs. in
  implements a simulation mode that takes commands through a socket and
  writes back numbers (e.g. the matrix). this is mostly undocumented.
- a command plugin 'mstat' that prints out the matrix memory footprint,
  i used that whan playing with node ordering schemes

a nice plugin to have would be a 'dumpacmatrix|acx' command. it should
be easy to implement, i've not done it, as i've got a 'dm' switch for
.ac... in any case feel free to copy and paste parts from the attempts
