MATLAB: How to find a corresponding matrix value

matrix

I have two matricies, Q and W, and I calculated the values of Q from the values of W. I then found the maximum values of each row in Q, but I also need to find the corresponding values of W from the other matrix and I'm not sure how to do that.

You can get the corresponding values in W as follows

[mQ,idx] = max(Q,[],2,'linear')
W(idx)

U = triu(D_final);
L=tril(D_final);
w = 1:0.01:1.99 ;
N = length(w) ;
iwant = zeros(N,1) ;
for i = 1:N
    P=(1/w(i))*D_dig + L;
    T = (w(i)-1)/w(i)*D_dig + U;
    lambda=eig(-L \ T);
    iwant(i) = norm(lambda) ;
end
[val,idx] = min(iwant) ;
w(idx)
