Hi all,

I just downloaded and installed octave-2.1.51 (i686-pc-linux-gnu). 
I ran into the following error, which may or may not be a bug.

BUG DESCRIPTION:
octave:1> rank(eye(1))
error: octave_base_value::array_value(): wrong type argument `bool'
error: evaluating assignment expression near line 49, column 10
error: called from `rank' in file `/usr/share/octave/2.1.51/m/linear-algebra/rank.m'

I seem to have the same error if I pass any vector:
octave:2> rank([1,2])
error: octave_base_value::array_value(): wrong type argument `bool'
error: evaluating assignment expression near line 49, column 10
error: called from `rank' in file `/usr/share/octave/2.1.51/m/linear-algebra/rank.m'

If instead, I supply a matrix the result is correct:
octave:2> a=[1,2;1,1];rank(a)
ans = 2


MACHINE & INSTALLATION DETAILS:
uname -m = i686
uname -r = 2.4.18-4GB
uname -s = Linux
./configure --prefix="/usr" --enable-shared --enable-lite-kernel --enable-rpath

"make" and "make install" went fine.

BUG FIX:
unknown

Thanks,
	Gabriele Pannocchia
