Import txt file into MATLAB for Comparison of 2 files to measure bit errors

Hello Support team,

I want to import txt file into MATLAB which includes bianry data. I have attached the 1.txt file for your reference. The file includes very large binary data (1010) . I want to compare the bit errors between 2 different .txt file same as 1.txt.

Kindly request you to guide. I have used importdata function. but, it does not create proper array as 1.txt file does not have data in vertical position.

Awaited your feedback

B1 = fileread('1.txt') - '0';
B2 = fileread('2.txt') - '0';

L1 = length(B1);
L2 = length(B2);
if L1 ~= L2
   fprintf('first file is %d entries but second file is %d entries. Ignoring extra\n');
end
L = min(L1, L2);

where_not_equal = find(B1(1:L) ~= B2(1:L));

hello

try this :

a = readfile('1.txt');

% or 

a = freadtxt('1.txt');

[Walter Roberson]

... this looks like a relatively expensive operation compared to just fileread() of the file.
