M=[a,b,c,d]
c=nchoosek(M,3);
c=c(sum(c(:,1:2).^2,2)-c(:,3).^2==0,:);
if isempty(c)
flag = false;
else
flag = true;

function flag = isTherePythagoreanTriple(a, b, c, d)
flag = false;
com_bin = nchoosek([a b c d],3);
com_bin = com_bin(:,1) .^ 2 + com_bin(:,2) .^ 2 == com_bin(:,3) .^ 2;
flag = logical(sum(com_bin));
end
