I'm trying to convert the text into binary and then i want to make the 4 bits chunks.

But the problem is that how to make the total size at the output for example: 001010101010001110101110111010110101.

its mean that i have only 1 row and 36 columns.

but i can't do it.

please help me out!

% I'm trying to convert the Hello World into binary
message = ('Hello world');
A = dec2bin(message, 8);          % Now to convert the charactors into 8 Bits using ASCI.
[r c]=size(A);
cc=struct([]);
A=convertCharsToStrings(A);
for j=1:1:r;
    z=A(j,:);
    cc=cat(2,cc,A(j,:));
end
disp(cc);

Is this what you are going for?

message = 'Hello world';
A = dec2bin(message, 8);
cc = reshape(A.',1,[])

cc = '0100100001100101011011000110110001101111001000000111011101101111011100100110110001100100'

No, you didn't get my point dear.

[Voss]

Ok. Please describe what you want.

You said 1x36, but the result has 88 bits (11 symbols at 8 bits per symbol), so that's inconsistent.

You said chunks of 4 bits, but that would only allow encoding of 16 distinct symbols. And 4 bits per symbol with 11 symbols would be 44 bits, not 36.

Clearly I'm very confused. Can you please help me out by providing a sample message and corresponding output? The message can be shorter than 'Hello world' if that's convenient.

I want to covert the text into binary then make the 4 bits chunks and asign that chunks to any variable then check the size.

[Voss]

message = 'Hello world';
A = dec2bin(message, 8);
B = reshape(A.',4,[]).'

B = 22x4 char array
    '0100'
    '1000'
    '0110'
    '0101'
    '0110'
    '1100'
    '0110'
    '1100'
    '0110'
    '1111'
    '0010'
    '0000'
    '0111'
    '0111'
    '0110'
    '1111'
    '0111'
    '0010'
    '0110'
    '1100'
    '0110'
    '0100'

size(B)

ans = 1x2

22 4

message = 'Hello world';
A = dec2bin(message, 8)

A = 11x8 char array
    '01001000'
    '01100101'
    '01101100'
    '01101100'
    '01101111'
    '00100000'
    '01110111'
    '01101111'
    '01110010'
    '01101100'
    '01100100'

B = reshape(A.',1,[])

B = '0100100001100101011011000110110001101111001000000111011101101111011100100110110001100100'

Now make the 4bits chunks and then check the size.

"Now make the 4bits chunks and then check the size."

B = reshape(A.',1,[]);
C = reshape(B,4,[]).'

C = 22x4 char array

size(C)

ans = 1x2
