datahex = sprintf('%02x', data);
I have converted image into array named data and then converted into hexadecimal.
Now I want to apply AES algorithm on it. But at a time only 16 bytes are are required.
How to read 16 characters from this datahex then next 16 and so on until all have been read.

for K = 1 : 32 : length(datahex)
datasubset = datahex(K : K + 31);
... work with datasubset ...
end
Note here that it takes 2 hex digits to form one byte.
