Dear All,

Thanks for your time.

I am trying to find the best solution for an application, then trace back the subfunction which provide the calculation data and show which the subfunction is. e.g.

function [a]=b()
for i=1:2
 c{1}=d()
 c{2}=e()
 a=20+c
end
f=min(a)

subfunction 1 which is

function [c]=d()
c=2 
end

subfunction 2 which is

function [c]=e()
c=5 
end

I would want to show which subfunction is used once achieving the minimum result f, is it function d or function b?

Thank you very much for your help in advance.

Why don't you use something like

solution1 = 20 + d();
solution2 = 20 + e();
if solution1 < solution2
  f = solution1;
  disp('min result achieved with subfunction 1')
else
  f = solution2;
  disp('min result achieved with subfunction 2')
end
