How do i get my textbox to display the given value of my variable??

pongAxes = axes('color','black','XLim',[0 100],'YLim',[0 100]),...

annotation('textbox',[0.3,0.8,0.2,0.2],'color','white','dis(score(1))');

score = [0,0];

I don't see where you're trying to set the string property of anything. What is your goal? Do you want a legend or an annotation?

[Ankit]

what is dis(score(1)) in your command?

[Sebastian Obwoya]

I want an annotation. It was actually supposed to be written like:

annotation('textbox',[0.3,0.8,0.2,0.2],'string','(score(1))');

My purpose was to print out the first value (1) of my variable score[0,0] in my gamer, to make a scoreboard.

In that case the sprintf command is what you're looking for, as the cyclist already suggested in his answer. Read the documentation for an overview of all available formatting options.

I'm guesing that

dis(score(1))

is a variable you are trying to display. You need to convert that to a string -- just putting quotes around it won't work, as you have presumably discovered.

Try

sprintf('%8.2f',dis(score(1)))

to show what that string will look like. I'm guessing at the format. You could use '%d' if it is an integer, or try adjust the values I guessed at for a floating point. See the documentation for sprintf for lots of details.

You could also just use

num2str(dis(score(1)))
