i define my fiteness function for the GA using 'assignin' expression

function [y]=myfiteness(x)

assignin('base','na',x(1));

assignin('base','nb',x(2));

[~,~,Y]=sim('mymodel',[0,1]);

y=y(end,2);

after using otimtool for GA for the function , the running stops and a message apear in the running section of the optimtool which show the following ''the subcript indices must be integer positive or logical''

so how to solve this problem????????

thank you sir for your observation but in fact the variable is y, not Y as i wrote before, i made the mistake of writting while i was posting the question ,so there is variable to work with in the simulation.
