Allocating values in 1d matrix

B = p * ones(327,245,2, uint8); can i do it with a loop?

No need for for loops, especially ones that don't work. Simply use ones:

B = p * ones(327,245,2, 'uint8');

Try this:

p=uint8(0);
for L = 3 : -1 : 1 
    for row = 327 : -1 : 1
        for col = 245 : -1 : 1
            B(row, col, L)=p;            
        end
    end
end

It's a very inefficient way of doing it. I reverse the indexes to try to make it more efficient though. You should NOT want to do it this way.
