You can loop over the structure using the "for [val, key] = structure"
construct.


octave> M = [ 1, 2 ; 4 , 3 ]

M =

~  1  2
~  4  3

octave> save ( "file.dat", "M" )
octave> data = load ( "file.dat" )

data =
{
~  M =

~    1  2
~    4  3

}

octave> for var = data; endfor
octave> var

var =

~  1  2
~  4  3
