Convert a vector to single element

Hey

could someone tell me how to convert an vector to single element?

My code :

signal = [0];
  for i = 1:255-1
             signal(i) =  dec2bin(i,8)        
  end

i get this error "the error is " Unable to perform assignment because the left and right sides have a different number of elements."

i want to get this result

singal = [0000000,00000001,00000010,.............. Ets ]

how could do that ?

and thank you :D

Answer 1

[Andrei Bobrov]

signal = dec2bin((0:255)');

or

fullfact([2 2 2 2 2 2 2]) - 1;

in your case

for i = 256:-1:1
    signal(i,:) =  dec2bin(i-1,8);
end

Use cells

signal = cell(254,1);
for i = 1:255-1
    signal{i} = dec2bin(i,8);        
end
