 where C  = 1 and hence is omitted from the array.
        N
 Coefficients are stored in reverse order:
 coef[0] = C  , ..., coef[N-1] = C  .
            N-1                   0
 Calling arguments are otherwise the same as polevl().
 
 In the interest of speed, there are no checks for out of bounds arithmetic.
x - argument to the polynomial.coef - the coefficients of the polynomial.N - the degree of the polynomial.
