Galois Field Array to Exponential Array Conversion 1.0

This code converts a Galois Field array created using GF(2^m) for a given primitive polynomial into the 'exponential' notation, which you can use with gfrepcov() to binary if you wish.Uses the gf2dec() function internally.Example usage:>> genpoly = rsgenpoly(15,11)genpoly = GF(2^4) array. Primitive polynomial = D^4+D+1 (19 decimal) Array elements = 1 13 12 8 7>> gf2exp(genpoly, 4, primpoly(4))ans = 0 13 6 3 10Showing this RS Polynomial is of form: X^4 + A^13*X^3 + A^6*X^2 + A^3*X + A^10, which is how you see it displayed in text books etc.
