What is your question? Is this homework? if so, then it is time to do your work.
If you need to generate a spline, then surely spline.m is the answer, or pchip.m, or perhaps have a go at spapi.m. So I'm not at all sure what is the actual question here, or at least the reason behind your question. Surely if I wanted to fit an interpolating spline, I would have started with spline.m.

I'm attaching my spline and polyfit demos. Adapt as needed.

As you know, with splines you get a new polynomial between every pair of points.
