<p class="refpurpose">This function is used to truncate the higher order zeroes in the given polynomial equation</p></div>
<div class="refsection"><h3 class="title">Description</h3>
<p class="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 > d + 1, where d is the degree of the polynomial, that zero is removed</p>
