## POLYINT Polynomial Coefficient Integration

Section: Optimization and Curve Fitting

### Usage

The polyint function returns the polynomial coefficients resulting from integration of polynomial p. The syntax for its use is eitherpint = polyint(p,k)

or, for a default `k = 0`

,

pint = polyint(p);

where `p`

is a vector of polynomial coefficients assumed to be in
decreasing degree and `k`

is the integration constant.

### Example

Here is are some examples of the use of`polyint`

.
--> polyint([2,3,4]) ans = 0.6667 1.5000 4.0000 0

And

--> polyint([2,3,4],5) ans = 0.6667 1.5000 4.0000 5.0000
