No, but I have a list of all of the functions in Matlab 2007b core and
the split between those that are implemented in Octave and those that
aren't.. Makes it easy to find the low hanging fruit.. the
dlmread/dlmwrite, etc functions should be ported from octave-forge and
are already in a very good state in octave-forge itself. There are also
a fair few other functions that might be ported from octave-forge and so
those are the things I'd do first as the code already exists and its
just a matter of coding style, texinfo help and checking for matlab
compatibility.
