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 either 
 pint = 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. Contributed by Paulo Xavier Candeias under GPL

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
