You've left us to do a lot of guessing as to what you want, but here's my guess,

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

When I run your code, I get a 512x4 matrix, not a 256x4x2 matrix.
>> whos B
Name Size Bytes Class Attributes
B 512x4 32768 double complex
Are you just trying to get a result in which B(:,:,1) contains all 256 combinations and B(:,:,1)=B(:,:,2)? If so, I don't know why you are duplicating the data, but just take my initial proposal and modify it as follows

if i want to retain the same size of 512x4 what do i have to modify.
