Just divide each value on your vector by the first value and then multiply by $100$ : $$y = (3100, 3110, 3120, 3110, 3115)$$ I guess what you're looking for is : $$(y/3100) * 100 = (100.00, 100.32, 100.64, 100.32, 100.48)$$ Edit : Just realize you also want the series to end at 100 ? If so, it looks like a Brownian bridge is what you might be looking ...
