I have a 8 byte input signal to a model. I want to extract every byte of that signal. How can I do it?

These two MATLAB functions might be of help:
str = dec2bin(d,n) produces a binary representation with at least n bits.
str = dec2hex(d, n) produces a hexadecimal representation with at least n digits.

I think this may be what you are after, converts a double to a byte array.
Data_In = double(floor(rand(1)* 10000)); %test double
Byte_Array = typecast(uint64(Data_In), 'uint8') %get byte array
I have only had MATLAB for a couple of days so am extremely new to it. I'm sure that this will most probably not be the ideal way to do this, not sure.
You may need to reverse the array depending on your endian preference.
