Costas array or just Welch array, is a Costas array generated using the following method, first discovered by Edgar Gilbert in 1965 and rediscovered in 1982 by Lloyd R. Welch. The Welch–Costas array is constructed by taking a primitive root "g" of a prime number "p" and defining the array "A" by formula_1 if formula_2, otherwise 0. The result is a Costas array of size "p" − 1. Example: 3 is a primitive element modulo 5. Therefore, [3 4 2 1] is a Costas permutation. More specifically, this is an exponential Welch array. The transposition of the array is a logarithmic Welch
