Fellow gretl users, There's a new version of my matlab_utilities function available. It now includes an "eye()" function that mimics the Matlab/Octave version. In particular it allows for eye(r,c), appending rows or columns of zeros to an identity matrix if r > c or r < c, respectively. Note that gretl's native I() function now has this behavior as of a few days ago (thanks, Allin!). If any of you have ideas for additions to this package that'd make your Matlab/Octave-to-gretl conversion easier, or any other comments on this package, please let me know (off list if you like).
