indexing in the nested loop
显示 更早的评论
sum_y_2_s=0;
sum_x_2_s=0;
for s=0:1:T-1
sum_y_2_s(s)=sum_y_2_s;
sum_x_2_s(s)=sum_x_2_s;
for z=s:1:T-1
sum_y_2_s(s)=sum_y_2_s(s)+y.^(z-s);
sum_x_2_s(s)=sum_x_2_s(s)+x.^(z-s);
ratio_1=(sum_y_2_s(s)./(sum_x_2_s(s)+K^(1/gamma)*x.^(T-s)));
end
if ratio_1<1
s_asterisk=s(end);
return
end
end
How should I index loop correctly. It shows
Array indices must be positive integers or logical values.
Error in opt_ret_positive_wealth (line 18)
sum_y_2_s(s)=sum_y_2_s
I am trying to find this ratio.
Thank you very much

sx = 0;
sy = 0;
for s = T-1:-1:0
sx = sx + x^(T-1-s);
sy = sy + y^(T-1-s);
ratio(s+1) = sy/(sx+K^(1/gamma)*x^(T-s));
end
