As I just wrote to the developer's list and after reading John's link I 
agree Octave's cov is improved in comparison to Matlab's cov (it seems 
to me that to do in Matlab what Octave does you need a loop), so I 
suggest not necessarily to patch the function but to handle with what is 
for many matlab users a counter intuitive behavior, i.e., either one of 
these:

1) Change Octave's function name, (perhaps cov2 or cov_i, for "improved").

2) Insert a warning in the cov's help to drag attention to a different 
behavior than in Matlab.

If you want to make a version of cov compatible to Matlab I think my 
patch is not enough and this will degrade the advantages of Octave's cov 
function, i.e., it is not advisable... I take thus the patch suggestion 
back and rather suggest to modify cov's help as I wrote to the 
developers list... Saludos, Ismael.
