I have a text file with byte data (example: 36 90 75 ...). Now I want to read this text file and convert it to a 8 bit vector. I'm using the below code to do the same.

input = textread('byteData.txt');
output = de2bi(input);

output from my code:

       0     0     1     0     0     1     0
       0     1     0     1     1     0     1
       1     1     0     1     0     0     1

Expected output: I do not need the output in matrix format, but I need them as a vector and in 8 bit format as shown below.

0     0     0     1     0     0     1     0     0     0     1     0     1     1     0     1     0     1     1     0     1     0     0     1

Thanks, this works partially. The output 3x7 matrix is concatenated to form a 1x21 vector, but I want the output 3x7 matrix to be converted to 3x8 matrix first so that the reshape command can produce a 1x24 vector.
