bit operations -- are they possible? |

Hello all,
I have an older FORTRAN program for demultiplexing sampled data files.
In these multiplexed files, consisting of 16 bit words, each word
contains a 12 bit value and a 4 bit channel number.
The problem with the FORTRAN program is that it cannot handle files
larger than 32 MB. therefore I would like to let Octave handle the
demultiplexing instead.
Is it possible to use Octave for "sifting" out the value and the
channel number respectively, or do I have to use C/FORTRAN for this?
That is, is it possible to rewrite my old program as an Octave m-file?
Since I wrote this message I have found out that I could use the
string routines bin2dec and dec2bin. The question is then, would an
m-file using these routines be painfully slow? Is there anyone with
experience in doing these operations?
Thanks for any input on this!
Bernt
