Looking at this page:
http://octave.sourceforge.net/doxygen/html/classdim__vector.html
it seems that dim_vector is not an Array<octave_idx_type>. Is to the
constructors, I'm guessing that
dim_vector (octave_idx_type n)
returns a dim_vector of length n, so you can do something like
dim_vector dims (4);
dims (0) = 5;
dims (1) = 6;
dims (2) = 7;
dims (3) = 8;
to create a dim_vector with the values [5, 6, 7, 8].
dim_vector (octave_idx_type r, octave_idx_type c)
however (I'm guessing again) returns a dim_vector with the values [r,
c]. The constructor with three arguments probably works like the one
with two arguments.
