Galois Field Array to Decimal Array Conversion

convert fg array to decimal numbers

Description

This code converts a Galois Field array created using GF(2^m) for a given primitive polynomial into a decimal array that can be used within typical .m file coding.
Example:
gfArray=gf([0:31],5,37);
DecArray=gf2dec(gfArray,5,37)

You could add a "break"-statement after the match is found and assigned to the output vector. This will stop the inner loop from maken useless loops.

I tried to run the script by matlab 2006 but i get an error like this
Error in ==> gf2dec at 18
GFInput = GFInput(:)'; 1382716070116605500000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000orce a row vector
