Hello, help me to solve this. I'm not into Matlab but doing this just for my assignment purpose. Had googled it but don't understand.
i=0:0.1:1;
for i = i
xt(i) = @(t) (-0.05)*t(i)^5+0.25*t(i)^4+t(i)+2-exp(-t(i));
yt(i) = @(t) t(i)^3+1;
zt(i) = @(t) (0.25*t(i)^4)+t(i)-exp(-t(i));
end

It is clear from the error that your index should be positive integer ("Integers that are greater than zero are positive integers" i.e. 1,2,3...etc)

t=0:0.1:1;
nt = length(t) ;
xt = zeros(nt,1) ;
for i = 1:length(t)
xt(i) = (-0.05)*t(i)^5+0.25*t(i)^4+t(i)+2-exp(-t(i));
yt(i) = t(i)^3+1;
zt(i) = (0.25*t(i)^4)+t(i)-exp(-t(i));
end
Actually you can do the same without loop.
i=0:0.1:1;
xt = (-0.05)*t.^5+0.25*t.^4+t+2-exp(-t);
yt = t.^3+1;
zt = (0.25*t.^4)+t-exp(-t);
