clear, clc
a = [0 1 0 0 0 0 0 1];
b = [0 0 1 1 0 0 1 1];
c = xor(a,b);
%Write encoded message to a text file
fid = fopen('mycode.txt','w'); %Opens the file for write access
fwrite(fid,c);
fclose(fid);
disp(c);
%%
%Read and decode the encoded message from a text file
fid = fopen('mycode.txt','r'); %Open the file for read access
c = fread(fid);
fclose(fid);
a = xor(c,b);
disp(a);
I'm not sure why the code isn't displaying the decoded message, which should be [0 1 0 0 0 0 0 1]

fread() returns a column vector by default.
c = fread(fid) .';

Neshant, as Walter has written. You need to use .' operator after the fread() call

Alternately you can use
c = fread(fid, [1 inf]);
