Calling multiple .m files into separate function

function [B, H] = IsStable(polynomial)
if polynomial ~= AllNonZero(polynomial(false))
B=0;
H=[];
elseif polynomial ~= AllSameSign(polynomial(false))
B=0;
H=[];
else
H=HurwitzMatrix(polynomial);
pm = length(H);
for i=1:pm
minor(i)=det(polynomial(1:i,1:i));
end
if minor(i)>0
B=1;
else
B=0;
end
end
I am trying to calculate the stability of a Hurwitz Matrix by checking if the principle minors are more than zero. Any sugestions to improve the above code as it is not working when I call three separate .m files e.g. AllNonZero, AllSameSign and HurwitzMatrix? Thank you.

If AllNonZero is false then isn't the matrix all 0 or at least a row of 0?
