Have a look at the format function, for example try:
format short g
disp(im)
HTH,

DISP tries to be smart and occupy as small space in the command window as possible. If all the data have a magnitude far appart from 1.0, DISP rescales the values and shows the scaling factor on top of the values. Possible solutions:
format long g
or
fprintf([repmat('%g ', 1, size(im, 2)), '\n'], transpose(im));
