Permutations

I have three vectors;

x = (-1:0.0625:1)
y = (-1:0.0625:1)
z = (-1:0.0625:1)

and I would like to output all teh permutations from these vectors which is obviously a matrix which is 33x33x33 however, I dont know how to do this in matlab

any help or advice would be greatly received
many thanks in advance
