   <title>Description</title>
   <para>
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 &gt; d + 1, where d is the degree of the polynomial, that zero is removed
