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.

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?
