Hello!

My math knowledge is quite far away in history, so I need help with how to compute
coefficients A..H for rational function using alglib.

Functions are:
z = y+(A + B*x + C*x^2) / (1 + D*x + E*x^2)
and
v = F*z + G*z^2 + H*z^3

Given is set of 8 distinct measured points [y,x].
Measured values are in integer in range 2^-15 .. 2^15

This is practical problem needed for calibrating linearizing function of signal conditioner chip.

Thank you.
