Hi everyone, how can I created 5 diffrent vectors based on:

n = [2 4 8 16 32]

if n = 2, N = [1/2 1/2]

if n=4, N = [1/4 1/4 1/4 1/4]

so on with 8 16 and 32

Please help me

for i=1:numel(n)
  N{i} = 1/n(i)*ones(1,n(i));
end

You can use the repmat function.

n=2;
N = repmat(1/n,1,n)
>> [0.5 0.5]

Here's one way:

n = [2 4 8 16 32];
N = cell(numel(n),1);
for k = 1:numel(n)
    N{k} = repmat(1/n(k),1,n(k));
end
celldisp(N)
 
N{1} =
 
    0.5000    0.5000

N{2} =
 
    0.2500    0.2500    0.2500    0.2500

N{3} =
 
    0.1250    0.1250    0.1250    0.1250    0.1250    0.1250    0.1250    0.1250

N{4} =
 
    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625    0.0625

N{5} =
 
  Columns 1 through 22

    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312

  Columns 23 through 32

    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312    0.0312
