mgorth usage

Hi,
I was trying to define if Octave has Gram-Schmidt defined. The only
thing I find is the function mgorth.
Sadly there are no usage examples nor demos and I fail to understand
the help string.
"Orthogonalize a given column vector X with respect to a given
     orthonormal basis V using a modified Gram-Schmidt
     orthogonalization."

If V is already an orthonormal basis, how can one find an extra
orthogonal vector? I think it should say
"Orthogonalize a given column vector X of size D-by-1 with respect to
a given orthonormal set V of size D-by-N, with D>N, using a modified
Gram-Schmidt
     orthogonalization."

Is that correct?
