how isolate?

hi, I converted decimal no. (10) into binary using x=dec2bin(10,15)=000000000001010

i want to isolate each 5 bits alone, then convert it again into decimal . I don't know how isolate each 5 bits alone.

thanks

v = 10;
x = dec2bin(v, 15);               % '000000000001010'
y = transpose(reshape(x, 5, 3));  % ['00000'; '00000'; '01010']
bin2dec(y)                        % [0, 0, 10]

Or without the slow step over the binary string:

floor(rem(v ./ [1, 32, 32*32], 32))

Can you clarify your question? If you want to extract portions of x you can just index:

x(1:5)
x(6:10)
x(11:15)

You could even reshape into 5-character blocks: reshape(x,5,[])'
