My annotation of Greek letters fails with capital letters and without them. Any answer?

>> Tbox=annotation('textbox',[.13,.39,.17,.085],'String','\alpha \beta \gamma \Gamma',...
' \delta \Delta \epsilon \zeta \eta \theta \Theta \iota \kappa \lambda \Lambda',...

You can't split a string over multiple lines. A quoted string literal must be all on one line. Try this:

Tbox=annotation('textbox', 'Position', [.13,.39,.17,.085],'String','\alpha \beta \gamma \Gamma \delta \Delta \epsilon \zeta \eta \theta \Theta \iota \kappa \lambda \Lambda \mu \nu \xi \pi \Pi \rho \sigma \Sigma \tau \upsilon \Upsilon \phi \Phi \chi \psi \Psi \omega \Omega',...
'BackgroundColor',[.5,.5,1])

Using for example

Tbox=annotation('textbox', 'Position', [.13,.39,.17,.085],...
'String',...
'$$\alpha \beta \gamma \Gamma $$',...
,'interpreter','latex')

and doing this in several Tbox annotations gives desired results. Thanks!
