start index in matrix with zero

how i start indexing in mAtrix from 0?

for M=1:1:m-1
       A1=A*x2(:,M);
       A2(:,M)=round(mod(A1,N));
     end
for M=1:m-1
    ss=A2(1,M)
    jj=A2(2,M)
 a4(ss,jj)=A2(3,M);
                  end
index for a4 come 0 .i cant change it. how i use zero index?

You could use this customized matrix type that uses zero-based indexing

but I don't really recommend it. Why not just do

 a4(ss+1,jj+1)=A2(3,M);
