gftrunc This function is used to truncate the higher order zeroes in the given polynomial equation A is considered to be matrix that gives the coefficients of polynomial GF(p) in ascending order powers A = [1 2 3] denotes 1 + 2 x + 3 x^2 AT=GFTRUNC(A) returns a matrix which gives the polynomial GF(p) truncating the input matrix that is if A(i)=0, where i > d + 1, where d is the degree of the polynomial, that zero is removed Pola Lakshmi Priyanka, IIT Bombay
