Question: Minors of a Square Matrix

Hi,

given a n*n Square Matrix (n is known), what is the easiest way to calculate all minors of this matrix ? There is a minor command in LinearAlgebra, but it seems to refer only to the first minor, that are the determinants of the reduced (n-1)*(n-1) Matrix. But I want the minors of a given size, specified by me. An application would be a test of definitness (Sylvester's Criterion). Using Maple13

 

Thanks
