Hello, I am trying to run an optimization so i get my S function at some biunds as shown bellow.
I got the error from the optimization.
Where did i go wrong formulating the SOLVE function?
Thanks.
Solving problem using gamultiobj.
Infeasible individuals are present in the final population.
Optimization terminated: average change in the spread of Pareto solutions less than options.FunctionTolerance.
Constraints are not satisfied within constraint tolerance.
Error using optim.problemdef.OptimizationProblem/solve
Unable to perform assignment because the size of the left side is 1-by-100 and the size of the right side
is 10-by-10.
Error in optim2 (line 46)
[sol,fval] = solve(prob);

Hi,
Thanks for posting this and apologies for stumbling across an internal bug which we'll fix as soon as possible.
As a workaround
Add this function to the bottom of your code
function out = convertToRow(S, E_opt_amp,E_opt_ph)
out = S(E_opt_amp,E_opt_ph);
out = out(:)';
end
Change this line
cam=fcn2optimexpr( S,E_opt_amp,E_opt_ph);
to
cam=fcn2optimexpr( @(E_opt_amp,E_opt_ph)convertToRow(S, E_opt_amp,E_opt_ph) ,E_opt_amp,E_opt_ph);
Your code should now run.
Hope this helps!
Paul
