How to create 3D sine array?

My question is simple. I want to create a sine function that is 1:1:1000 in size. Here is the code I have so far:

Fsam = 30;                          % Sampling Freq
Amp = 1;                      
Freq = 1;                        

Time = [0:1:1000-1];

Sig = Amp*sin(Freq*2*pi*Time);    %Signal

This will create an array "Sig" that is size (1x1000). How do I extend this to a three dimensional 1x1x1000 array? Your help is greatly appreciated.

   reshape(Sig,1,1,numel(Sig))

hi Sarah,

first the time axis is not properly sampled Fs=30; Time = [0:1/Fs:1000-1/Fs];

Can i ask you what is the purpose of adding Singleton dimension?
