RLaB implements horner's scheme for polynomial evaluation in its built-in function ''polyval''.
What is important is that RLaB stores the polynomials as row vectors starting from the highest
power.
This said, solution to the problem is
<lang RLaB>
>> x = [-19, 7, -4, 6]
</lang>
=={{header|Ruby}}==
<lang ruby>def horner(coeffs, x)
