Gets the polynomial coefficients at the specified index.
During data fitting, one polynomial is generated for each adjacent pair of unique x-values. Accordingly, the number of generated polynomials will be one less than the knot count.
The order of the polynomials is determined by the data-fitting function. N+1 coefficients will be generated per polynomial for an order N data fit.
