Break in the title

How can I break this title into multiple lines? The other examples on mathworks mostly deal with sentences in the title or may be I missed something! Thanks.

str= {' Parameters:',['S_0=' num2str(S0),', I_0=' num2str(I0),', C_0=' num2str(R10),', A_0=' num2str(R20)...
    ', \alpha=' num2str(alpha),', p_1=' num2str(p1),', q_2=' num2str(p2),', p_3=' num2str(p3),', p_4=' num2str(p4),', p_5=' num2str(p5) ...
     ', b=' num2str(b),', a=' num2str(a),', d_a=' num2str(da),', d_i=' num2str(di), ', d_h=' num2str(dh)...
     ', g=' num2str(g),', m=' num2str(m),', b_s=' num2str(bs),', F=' num2str(F)
]
};

Use sprintf to reduce the number of num2str and make the coding easier. For example:

str= {' Parameters:',['S_0=' num2str(S0),', I_0=' num2str(I0),', C_0=' num2str(R10),', A_0=' num2str(R20)...
    ', \alpha=' num2str(alpha)}

can be written in two lines as:

 str=sprintf('Parameters: [S_0=%g, I_0=%g, C_0=%g, A_0=%g, \n \\alph=%g',S0,I0,R10,R20,alpha)

Note the \n for newline character

If you still want to use a cell array, then you can make a break as follows

str={'line 1';'line 2'}

Thanks for your help. Previously, I was using these parameters to make a text box in a figure (see code below). Would it be possible to do the same thing with sprintf?

str= {' Parameters:',['S_0=' num2str(S0),', I_0=' num2str(I0),', C_0=' num2str(R10),', A_0=' num2str(R20)...
    ', \alpha=' num2str(alpha),', p_1=' num2str(p1),', q_2=' num2str(p2),', p_3=' num2str(p3),', p_4=' num2str(p4),', p_5=' num2str(p5) ...
     ', b=' num2str(b),', a=' num2str(a),', d_a=' num2str(da),', d_i=' num2str(di), ', d_h=' num2str(dh)...
     ', g=' num2str(g),', m=' num2str(m),', b_s=' num2str(bs),', F=' num2str(F)
]
};
annotation('textbox',...
    [0.15 0.35 0.8 0.25],...
    'String',str,...
    'FontSize',14,...
    'FontName','Arial',...
    'LineStyle','-',...
    'EdgeColor','k',...
    'LineWidth',2,...
    'BackgroundColor',[1  1 1],...
    'Color',[0 0 0],'FitBoxToText','on');

The output of sprintf is just a string. So yes, it is possible. Perhaps there are some circumstances when a cell array is a better way to store a multi-line string, but I can't think of any.

Try this simple example:

str=sprintf('A%g\nB%g',1,2)
annotation('textbox',[0 0 .1 .1],'string',str)

" Perhaps there are some circumstances when a cell array is a better way to store a multi-line string, but I can't think of any"

Cell arrays make it trivial to use indexing to select which lines get displayed. For example, I used this for the warning text in cubehelix_view:

True, that's one example

Another nice FEX function added to my arsenal. Already using your colorbrewer and matplotlib. They really make life easier when producing figures for scientific papers, so thanks for those!
