Hi.
I have Octave 3.0.1 from Debian testing "Lenny" repository.
The ranks function doc says that it returns a _column_ vector, instead
the function returns a _row_ vector.
HOW TO REPPRODUCE THIS BUG
Step #1
If I type:
help ranks
I read:
"If X is a vector, return the (column) vector of ranks of X adjusted
for ties."
(it says _column_ vector)
Step #2
If I type:
"size (ranks (1:3))"
I get:
ans =
1 3
I suppose this happened when ranks was converted for use with
NDArrays... Though to me the new behavior makes more sense and I'd
propose fixing the documentation string instead with the attached patch.
This should be applied to both 3.1.51+ and 3.0.1+
