Hi,
The part where you read the txt file looks alright, maybe redundant.
fgelt already gives you a string so instead of calling sscanf on top
of fgetl seems to be useless. If you want to read formatted input, you
could use fscanf.

There are many functions in your script that will not work in Octave.
Are you sure the failure is not in one of those?
