Details:

On ver 3.4.0, cor fails with 1 argument. corrfcoef works properly. I believe
this also affects the devel sources based on inspection, but I have not
checked with a compiled version.

Code that shows the problem:
octave:1> a = rand(10,2);
octave:2> cor(a)
error: cov: X and Y must have the same number of observations


A possible fix: in cor.m, change

function retval = cor (x, y = [])

to 

function retval = cor (x, y = x)
