When trying to create a message box with a custom title, it does not show up for me.
CreateStruct.Interpreter = 'tex';
CreateStruct.WindowStyle = 'modal';
str_angle = sprintf('%.3f', angle);
str_true_vector_mag = sprintf('%.3f', true_vector_mag);
f = msgbox( {['Angle: ' str_angle '\circ'];['Distance: ' str_true_vector_mag ' m']} , 'Results' , CreateStruct);
I want the title to be 'Results', but for some reason the output does not show the title.
Thank you.

Your "Results" text isn't showing because the window is too small. Try making it wider as such:
angle = 30;
true_vector_mag = 15;
CreateStruct.Interpreter = 'tex';
CreateStruct.WindowStyle = 'modal';
str_angle = sprintf('%.3f', angle);
str_true_vector_mag = sprintf('%.3f', true_vector_mag);
f = msgbox({['Angle: ' str_angle '\circ'];['Distance: ' str_true_vector_mag ' m']} , 'Results' , CreateStruct);
f.Position(3) = 200; %<== MAKE FIGURE WIDER

Note that the figure titles are handed off to the operating system being used, so the display will vary. On Mac El Capitan, 'Results' does show up, but Windows or Linux might display differently.

That's a good point - @Kingsbury, the solution I gave may not be robust for other OS with different display settings. Make sure to test it before deploying any software to others.
In Windows, small message boxes do have the title hidden behind the [Minimize, Expand, Close] symbols, which by default are spaced out a lot... A workaround would be to show the text "Results:" along the message inside the msgbox.
