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)))
