POLYINT Polynomial Coefficient Integration

Section: Optimization and Curve Fitting


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


Here is are some examples of the use of polyint.
--> polyint([2,3,4])

ans = 
    0.6667    1.5000    4.0000         0 


--> polyint([2,3,4],5)

ans = 
    0.6667    1.5000    4.0000    5.0000
