The precedence relations of a precedence grammar can be precisely described by a two-dimensional precedence matrix. Often the information in the matrix can be represented more concisely by a pair of vectors, called linear precedence functions. A new algorithm is presented for obtaining the linear precedence functions when given the precedence matrix; this algorithm is shown to possess several computational adavantages.
