For loop error: Subscript indices must either be real positive integers or logicals

I am executing a for loop but it gives following error at time 0.6:

T_o=[0;0;0];
T_d=[0;0;0];
T_l=[0;0;0];
out_n=zeros([],3);
for t=0:0.1:10
    T_o = [0.05*(10-t);0.04*(10-t);0.03*(10-t)];
    T_e=T_d-T_o;
    T_e=[t*10 T_e'];
    a = sim('PD_control','SimulationMode','normal');
    out = a.get('T_u');
    out_n(t*10+1,:) = out(2,:)
end

The Simulink file called by this code is attached here.

T_o=[0;0;0];
T_d=[0;0;0];
T_l=[0;0;0];
out_n=zeros([],3);
tt=0:0.1:10 ; 
for i = 1:length(tt)
    t = tt(i) ; 
    T_o = [0.05*(10-t);0.04*(10-t);0.03*(10-t)];
    T_e=T_d-T_o;
    T_e=[t*10 T_e'];
    a = sim('PD_control','SimulationMode','normal');
    out = a.get('T_u');
    out_n(i,:) = out(2,:)
end

Great! Exactly what I needed.

http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F

mat2str((find((0:0.1:10)*10-(0:100))-1)/10)

0.3 0.6 0.7 1.2 1.4 2.3 2.4 2.8 2.9 4.1 4.6 4.8 5.2 5.4 5.9 6.2

That is, 0.3 * 10 is not 3.0 exactly.

0.1 in binary floating point is not exactly 1/10, just the same way that in decimal 0.333...3 * 3 is 0.999...9 instead of 1

Thanks. Didn't know this before.
