void polyfit (
    const DT evalX [MAX_WIDTH],

    )

Calculates the polynomial fitting to the D degree of the discrete set of points in ‘evalPoints’.

Parameters:

DT
:	The data type of the points
D
:	The degree of the polynomial that will approximate the set of points.
MAX_WIDTH
:	The maximum synthetisable amount of discrete points.
evalX
:	values on the X axis of the set of points.
evalPoints
:	Set of points to be approximated.
sizeEval
:	Length of ‘evalPoints’, must be <= MAX_WIDTH
coefficients
:	Output polynomial coefficients that approximate ‘evalPoints’ to the D degree, in decreasing order of degree.
