hello guys!

I hope somebody can advise me with respect the next code, when I run it into embedded editor from simulink embedded block, I have the error that Variable 'pmin' is undefined on some execution paths.

How should I define it if p = uint16

Lmin = inf;
L = 0;
for k = 1:m
  % Nearest neighbour tour
  p = greedy(s(k),D);
  % Improve tour by 2-opt heuristics
  [p,L] = exchange2(p,D);
  % Keep best tour
if L < Lmin
   Lmin = L;
   pmin = p;
 end
end
% Output
p = double(pmin);
L = Lmin;
