public class Polynomial
extends Constants

Polynomial functions.

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

 Method Detail

### p1evl

```public static double p1evl(double x,
double[] coef,
int N)
throws ArithmeticException```
Evaluates the given polynomial of degree N at x, assuming coefficient of N is 1.0. Otherwise same as polevl().
```                     2          N
y  =  C  + C x + C x  +...+ C x
0    1     2          N

where C  = 1 and hence is omitted from the array.
N

Coefficients are stored in reverse order:

coef = 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.

Parameters:
`x` - argument to the polynomial.
`coef` - the coefficients of the polynomial.
`N` - the degree of the polynomial.
Throws:
`ArithmeticException`

### polevl

```public static double polevl(double x,
double[] coef,
int N)
throws ArithmeticException```
Evaluates the given polynomial of degree N at x.
```                     2          N
y  =  C  + C x + C x  +...+ C x
0    1     2          N

Coefficients are stored in reverse order:

coef = C  , ..., coef[N] = C  .
N                   0
```
In the interest of speed, there are no checks for out of bounds arithmetic.

Parameters:
`x` - argument to the polynomial.
`coef` - the coefficients of the polynomial.
`N` - the degree of the polynomial.
Throws:
`ArithmeticException`
