Extracting elements from a matrix based on the maximum position in another matrix

Hi, I have matrices A(100x96) and B(100x96). My aim is to find the value of element in A corresponding to position of max in B. [M, J]=max(B); % M gives max values and J gives position corresponding to max value of B. M & J have 1x96 dimension. Now I have to find values of A for position J. I know if manually I do like, A(J(1),1), A(J(2),2).. would give me required elements of A (but not suitable for large dimension). How to solve?Any suggestions. Thank you so much.

arrayfun(@(j,f) A(j,f), J,1:size(A,2))

a = rand(100,96);
b = rand(100,96);

[~,idx] = max(b);

result = a(sub2ind(idx,1:size(a,2)))
