I am trying to display both a text and image on simulink block using system object and matlab system. The code below help me display both an image and a text. However, I would like to display a portion of the text that changes based on some actions performed by the user.
maskDisplay = [ ...
'image(''logo1.png'');' ... % Show an image
'disp(''My Text'');' % Display some text in center.
];
Goal: For example:
disp(''My text'' + userInput);
where userInput is a variable received from the user; however doing it this way does not work. I replaced the + with a comma, and it still does not work. How can I achieve that?

Maybe try using sprintf with the names of your variables to create a string and then combine into a cell array of strings of different lengths?
string1 = sprintf('image("%s");', yourFileName) % Show an image
string2 = sprintf('disp("%s");', myText); % Display some text in center.
maskDisplay = {string1, string2}
