Hi,

Once you read the text data from your file, you can convert text to binary by using dec2bin function.

a = dec2bin("Some String");

The variable "a" will have the binary converted value.

For reading from text files you could refer to the following links of different read functions

https://www.mathworks.com/help/matlab/ref/fgets.html

Hope this helps.

dec2bin() will not work on string objects. It will work on character vectors (but remember that characters can have more than 8 significant bits.)

Answer 2

[Walter Roberson]

fid = fopen('FileNameGoesHere', 'r');
file_bytes = fread(fid, [1 inf], '*uint8');
fclose(fid);

%if needed
file_bits = reshape( (dec2bin(filebytes, 8) - '0').', 1, []);

file_bits would be a vector of 0 and 1 values.
