There exists an internal Octave variable called
which can be set to "true"
octave:1> implicit_str_to_num_ok = "true";
After you have set this, you can define
octave:2>str = ["abc";"def"]
97 98 99
100 101 102
where the matrix str is automatically converted to numeric type. Now
works if you have set the variable
do_fortran_indexing = "true"
If you want to set the type of a variable from 'numeric' to 'string',
you can use the function setstr()
octave:4> s2 = setstr(str)
s2 = adbecf
But this is maybe not what you want?

Yes they do, but do not work on every system. They are called
'dynamically linked functions' and you need the GNU dynamic linker 'dld'.
In my octave 1.1.0 manual you can find the relevant info in section 5.8
All the best,
