p1evl(double x,
double[] coef,
int N)
Evaluates the given polynomial of degree N at x,
assuming coefficient of N is 1.0.

polevl(double x,
double[] coef,
int N)
Evaluates the given polynomial of degree N at x.

Coefficients are stored in reverse order:
coef[0] = C , ..., coef[N-1] = C .

Calling arguments are otherwise the same as polevl().
