Need more info...did the Fortran program write a Fortran unformatted file as a default OPEN(lun,form='unformatted')? If so, there's a record structure that will have to be dealt with (Fortran unformatted files are _NOT_ C-like stream files but have internal record information to support operations like BACKSPACE). You'll have to read that information as well.
If, otoh, either a pre-F2003 extension was used (supported by every compiler I'm aware of in one form or another) or the F2003+ Standard mechanism has been implemented in the compiler and used, then all you need to do is to read the file and reshape since both Fortran and Matlab use column-major storage order.
