this is strange... this works on my computer (win64 running matlab7.7) but not on the servers, perhaps is some different behavior of histc in the newer version? (and why not use 'hist' or 'accumarray' instead?)

Just using inspection, I see a space in your function (between "function" and "x9") whereas your code predicts no spaces.

thanks for the help! it seems in my version textscan(fid,'%c','CommentStyle','%','Whitespace','') removes the spaces from the resulting string...
