i have two binary array 10011 and 01010, i want compare each binary and find the number of different and similar bits?

Answer 1

[James Tursa]

binary1 = 1st binary char vector
binary2 = 2nd binary char vector
number_of_similar_bits = sum(binary1==binary2);

thank you for answer James Tursa, but unfortunately didn't work with me

How do you initialize your binary array storing 10011

[James Tursa]

@Mahdi: Here are two examples with the binary values being character strings and double vectors,

>> binary1 = '10011';  % As character strings
>> binary2 = '01010';
>> number_of_similar_bits = sum(binary1==binary2)
number_of_similar_bits =
     2

>> binary1 = [1 0 0 1 1]; % As numeric vectors
>> binary2 = [0 1 0 1 0];
>> number_of_similar_bits = sum(binary1==binary2)
number_of_similar_bits =
     2

So, apparently you have something different from what I assumed. You need to tell us what this format is before we can help you.

My guess is on decimal numbers having been used, like ten thousand and eleven 10011

[Image Analyst]

Then how did he get 01010 if he was using numbers instead of strings?

Thank you James Tursa this work with me

>> binary1 = [1 0 0 1 1]; % As numeric vectors
>> binary2 = [0 1 0 1 0];
>> number_of_similar_bits = sum(binary1==binary2)

It is common for people to enter decimal values such as 01010 intending them to indicate binary, and then to get frustrated and confused when MATLAB removes the leading zeros.
