Short answer: get rid of all the ...
Long answer: I assume that at some point, the stuff after the ... was on a second line. ... means two things: the rest of the line is a comment, the remaining of the instruction is on the next line. In effect, what you have written is:
fprintf('something', fprintf('somethingelse', fprintf('anothersomething', else
else is not valid in this context.
