Take a look at the referencing to "prim_poly", "x", etc in the galois
type in octave-forge.. The code is in main/comm/ov-galois.cc where
"prim_poly" is referred to by the macro __GALOIS_PRIMPOY_STR, etc..
This code uses dotref to display the data only, not to set it.
Code I wrote that can actually change the values set in this manner is
in main/fixed/ov-fixed.cc where the key __FIXED_INTSIZE_STR can be used
to change the fixed-point representation.
Regards
David
