iter = 1;
while( Error > Tol )
...
out{iter} = PSO_EBW_SD(problem, params);
...
iter = iter + 1;
end
Just use a counter like above. Obviously you will need to update your code accordingly to reference out{iter} or assign it to out as you are now, use it as you are now and then put it in a cell array before the end of the loop.
This code is un-necessary though:
if Error <= Tol
break
if Error > Tol
continue
end
end
For a start the 2nd if will never execute because it is in direct opposition to the if statement it sits inside and the first if statement is superfluous because the while condition will pick this up at the start of the next loop anyway.
