Am trying to create some voting space for the synthetic model and i end up with "subscript indices must be either positive integers or logicals" Here's the similar code with less dimensions, for ex-

a = [-1.32 -2.56 -3.8;-4.2 -5.7 -6.23;-7.02 -8.4 -9.59];
rows =3;
columns =3;
w=ones(rows,columns);
vy = zeros(3,3);
for i =1:rows
    for j=1:columns
       low_v=floor(a(i,j));
       high_v=ceil(a(i,j));
       vy(i,a(i,j)-1)=vy(i,a(i,j)-1) + w(i,j);
    end
end

I understand that each index is having a negative values(which i mentioned intentionally) instead of a positive integer, but my goal is to get results for the negative values. Could someone help me out with the possible modification that i could the desired results Thank you so much in advance
