You've made some very nice contributions to octave lately. Thank you. For what it's worth, I've been inverting Galois matrices lately and I'm seeing about a 300x speedup using your gfinv function compared to the equivalent in Matlab.

Dear All,

I've just committed a fixed-point toolbox for octave to octave-forge.
The toolbox, creates numbers with a known number of bits before and
after the decimal point and then allows arbitrary mathematical
operations on them, taking into account the loss of precision at each
stage. This simulates a real limited complexity implementation of an
algorithm in an ASIC, and can be used to optimize the complexity (i.e
number of bits at each stage, and thus number of logic cells) of an
