You've left us to do a lot of guessing as to what you want, but here's my guess,
[c{1:4}]=ndgrid(p);
result=reshape(cell2mat(c),256,4);

i don't know what you exactly mean but i assumed the entries to the 3d matrix are the same as in the given vector, you can try the following code:
p=[1 -1 1j -1j];
for n=1:256
Matrix(n,:)=p;
end
Matrix(:,:,2)=Matrix(:,:,1);
