Algorithm 1 Matrix transform algorithm.
Input: Square matrix $M_1$
Output: Lower triangular determinant
1:	Count the size of $M_1$ which is composed of t rows and columns
2:	for$i=2$ to t do
3:	$M_1(i,:)=M_1(i,:)-2^{i-1}·M_1(1,:)$
4:	end for
5:	for$j=2$ to t do
6:	$M_1(:,j)=-M_1(:,1)+M_1(:,j)$;
7:	for $k=2$ to $j-1$ do
8:	$M_1(k,:)=M_1(k,:)-M_1(k,j)/M_1(j,j)·M_1(j,:)$;
9:	end for
10:	for $l=j+1$ to t do
11:	$M_1(l,:)=M_1(l,:)-2^{l-j-1}·M_1(j,:)$;
12:	end for
13:	end for
