I’m not certain what you mean by ‘minimum nonzeros elements’. This takes the row sum of the rows with nonzero elements and finds the row with the smallest row sum:
M = randi(51, 20, 5)-1;
[r0,~] = find(M == 0);
Mnz = M(setdiff([1:size(M,1)],r0),:);
[Mu, ix] = sort(sum(M,2));
Row_min_nz = is(x); % Row With Minimum Row Sum

M = randi(5, 6, 6) - 1;
[V, Index] = min(sum(M == 0, 2));

a = [2,2,3;0,2,5;1 2 3]
[row,column]=find(a==min(min(a(a>0))))
