I think you should change the data to uint8 or uint16 format.
I have uploaded the function with a very simple form, It is also suited for vectors.
you also can try CCRE,which is more general than the Shannon Entropy. if you prefer the double data type,the data is treated as continuous. http://www.mathworks.com/matlabcentral/fileexchange/41699-ccre-for-multi-modal-image-registration

This is nice for pictures. I try explain u what is my problem :) I have a couple of .wav files, and i transported to binary sequence. I record files with function: fs= 44100; #frequency intval = 2; #interval voicein = wavrecord(intval*fs,fs, 'int16'); #record transported into binary with function: wavbinary = dec2bin( typecast( single(wav(:)), 'uint16'), 16 ) -'0'; remove redundancy with function: wavbinary = bitand(wav*32768+32768,1) and i got "<88200x1 double>" file Now my problem is how i can calculate mutal info for two binary files :D
