Question

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)
