We develop two algorithms that nd a minimal polynomial of a finite sequence. One uses Euclid's algorithm, and the other is in essence a minimal polynomial version of the Berlekamp-Massey algorithm. They are formulated naturally and proved algebraically using polynomial arithmetic. They connects up seamlessly with decoding procedure of alternant codes.
