## Polynomial Factorization (Scripts) Publisher's description

### POLYFACT Polynomial FactorizationQ = POLYFACT(A) returns the factorization of polynomial A.

POLYFACT Polynomial Factorization
Q = POLYFACT(A) returns the factorization of polynomial A.

Input variable A must be a vector with integer coefficients in descending order. e.g. [3 7 2] represents 3*x^2+7x+2

Output Q is a cell array with each index being a polynomial factor, with integer coefficients in descending order.

If polynomial A cannot be factored it will be returned unchanged as the output.

As a sign convention, whenever possible the leading term for each polynomial factor will be positive.

EXAMPLE:
a=[-36 6 48 -21];
Q=polyfact(a)
%Q{1} = [-3]
%Q{2} = [2 -1]
%Q{3} = [6 2 -7]

a=[3 -3 1];
Q=polyfact(a)
%Q{1} = [3 -3 1]
