I have a GUI function that defines a few text boxes under the structure S. When calling to update the value of the text box named 'S.Text_for_display' within a seperate function called 'Speak' I recive the error 'Unable to resolve the name 'S.Text_for_display'.'.
function []=Speak(txt)
set(S.Text_for_display,'String','','LineStyle','none','FontSize',14,'FontName','Comic Sans... MS','FitBoxToText','off');
len=length(txt);
for i=1:len;
if i<=len;
Display(txt(1:i));
pause(.05);
else
Display(txt);
end
end
end

for i=1:len;
if i<=len;
Display(txt(1:i));
pause(.05);
else
Display(txt);
end
In a for loop that goes 1:len it is certain that i <= len so there is no point in having the if

The function does not know what "S" is. You need to pass it as an input.
And the font name 'Comic Sans MS' does not have ellipses (3 dots) in it.

Could you share the struct "S"? Use the paperclip button to attach.
How are you calling the function?
