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

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
