Web• Finite fields are called Galois fields. •Example: – Binary numbers 0,1 with XOR as “addition” and AND as “multiplication”. – Called GF(2). ... • Every Galois field has a primitive element, α, such that all non-zero elements of the field can … WebGalois field polynomial, specified as a row vector, character vector, or string. a can be either a Representation of Polynomials in Communications Toolbox or numeric vector. a and b must both be GF ( p) polynomials or GF ( pm) polynomials, where p is prime.

I think your code is OK, but you have two problems. First, the comments are wrong; you are keeping the exponent in the range 0-254, not 0-255. Second, your "trivial" test cases are wrong. In this field, think of numbers as polynomials whose coefficients you get from the binary representation of the ... foam sticks for boxing
