I am afraid that would mess up with negative numbers...
Try:

sed 's/\([0-9]*.[0-9]*\)\([-+]\)/\1e\2/' filename > newfilename

this asumes you have one number per row...
anyway, if it is easy to read this format in fortran, you can easily
wrap a small fortran program in a DLD function to call it from octave.
