read binary file into matrix

I have a binary file, that is encoded as hex. If I use fread on it I get a 8192x1 double with values like these:

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 9 69 48 48 50 50 69 55 50 54 57 09

these are hex values, so 69 is E for example. Now at the end there is an 09 (tab) and I would like that tab to indicate to go to the next cell in a matrix, so that when I read and process the file, I have all the data stored in a matrix. Now if this were a tab-indented file, I would just use importdata(...), but as it is in a binary, that I have to convert to a string, and then to a matrix, I can't figure out how to do it. Any ideas?

Pay attention to the 'source' and 'precision' options to fread().

is your friend

Example from, http://www.mathworks.com/help/matlab/ref/fread.html,

% Create the file
fid = fopen('magic5.bin', 'w');
fwrite(fid, magic(5));
fclose(fid);

% Read the contents back into an array
fid = fopen('magic5.bin');
m5 = fread(fid, [5, 5], '*uint8');
fclose(fid);
