How to break the infeasibility of solution for the function linprog?

Hello everyone,

I'm working on some heuristic algorithm wich has to return to choose another random initial state and run again.

Inside I loop while I have to solve at each iteration a linear programming by using the functon linprog.

How can I break the programme and return it to the initial state choice when there is no feasible solution to the linear programming problem without stopping the whole program?.

Thank you.

Can't you choose how to proceed depending on the linprog exitflag ?

sorry but I'm a new user of matlab. However, I know that the error is because of infeasibility reason. I read this https://fr.mathworks.com/help/optim/ug/linprog.html#buusznx-exitflag

but I don't know how to implement it on the program.

Thank you in advance.

[x,fval,exitflag,output] = linprog(___)
if exitflag > 0   % linprog was successful
    take action 1
else              % linprog was not successful
    take action 2 
end
