Follow-up Comment #2, bug #42671 (project octave):
Alright... an updated patch is attached that supersedes the first one.
Currently, Octave is incompatible to MATLAB in another way, *not* handled with
this patch. In MATLAB, the input arguments are interpreted strictly as stated
in the doc: columns are variables, rows are observations:
>> corr(1:4)
ans =
NaN NaN NaN NaN
NaN NaN NaN NaN
NaN NaN NaN NaN
NaN NaN NaN NaN
Octave, in contrast, makes an expection for vector input(s), always handling
each one as one variable with as many observations as it has elements. This
special case is not documented and may cause confusion. Personally, I prefer
stricter semantics whenever possible.
