MATLAB: Set all the values of row i to zero in two dimensional array.

Question

%Finding Neighbor

Nbr=zeros(n);

R=20;

for i=1:1:n

for j=i+1:1:n

distance=sqrt( (S(i).xd-(S(j).xd) )^2 + (S(i).yd-(S(j).yd) )^2 );

s(i,j)=distance;

s(j,i)=distance;

if distance< R

Nbr(i,j)=1;

Nbr(j,i)=1;

end

end

end

%% follwing gives no of neighbours of each i

for i=1:1:n

count(i)=sum(Nbr(i,:));

end

%%%%QUESTION%%%%%%

%%% How do I set the all the values of a row i to zero in matlab , some thing like this

Nbr(i,:)={0}

Answer 1

Given a numeric matrix Nbr:
