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!

clc;
close all;
clear alll;
% 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'

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.
