I have this:
d(:,:,i) = 0.005*sin(0.5*pi*t(i))*cos(0.5*pi*t(i))
i=1:Nt
t = linspace(0,100,Nt+1)
Nt=1000

Use
Nt = 1000
t = linspace(0,100,Nt+1)
d = 0.005*sin(0.5*pi*t).*cos(0.5*pi*t)
plot(t,d)
Any reason you are using a 3-dimensional array d ?

Not sure why you are trying to construct your signal like this. Take advantage of MATLAB's vector operations.
Nt = 100;
t = linspace(0,100,Nt);
d = 0.005*sin(0.5*pi*t)+cos(0.5*pi*t);
plot(t,d)
