Follow-up Comment #2, bug #30571 (project octave):
It seems that sparse diagonal matrices are excluded:
octave:1> typeinfo (speye (4))
ans = sparse matrix
octave:2> typeinfo (full (speye (4)))
ans = matrix
octave:3> matrix_type (speye (4))
ans = Diagonal
This was the reason to use matrix_type.
Marco
