In line 47 you're assigning the value to goodDots(id) like it's a one dimensional array but goodDots=false(zeros(1,nDots)); in line 29 creates something else. Shouldn't

goodDots=zeros(1,nDots);

be enough?

I have modified that but now the error is "Array indices must be positive integers or logical values". this error is present at the line 52

Are you sure that's the only error and not something within the drawFixation function itself? drawFixation doesn't seem to be an array.
