# polyval

Evaluate a polynomial.

## Syntax

y = polyval(p,x)

y = polyval(p,x,[],mu)

## Inputs

`p`- The coefficients of the polynomial to be evaluated, in descending order.
`x`- The values at which to evaluate the polynomial.
`mu`- Shift and scale factors to evaluate the polynomial for (x-mu(1))/mu(2).

## Outputs

- y
- The evaluated polynomial values.

## Example

Evaluate x^2 + 5x + 6 at various values.

`y = polyval([1,5,6],[0,1,2,3,4,5])`

```
y = [Matrix] 1 x 6
6 12 20 30 42 56
```
