Hi,

Help me to store the obtained output (minDist) in the workspace. You will find enclosed the function tsp_ga.m that I use.

Thanks in advance.

How are you currently calling this function?

Actually, My main goal is to save the output (minDist) in a vector, therefore I used the loop "for" which runs the function tsp_ga.m n times. So to do it I wrote the following code (be n=5):

if kk=1:5
  tsp_ga
  ss(kk)=minDist
end

But it gave the following error: " Undefined function or variable 'minDist'. Error in (line 4) ss(kk)=minDist_ ". So I think I need to store the output "minDist" from the function to the workspace.

The function tsp_ga returns a structure with lots of values in it. minDist is one of those values:

S = tsp_ga(...)
S.minDist

Or inside your loop:

if kk=1:5
    S = tsp_ga(...);
    ss(kk) = S.minDist;
end

This is explained quite well inside the function help, with both calling syntax and examples. You should read the help of every function that you use, because the help shows you how to use that function, and means that you do not have to guess and waste your time asking random strangers on the internet for help.
