Suppose I have a matrix, A=rand(5,5) and an array, b=[2,3]. How can I extract the A(2,3) element? I know a simple solution is A(b(1), b(2)), but the problem is that I may end up with a high dimensional A matrix and I do not want to write something like: A(b(1), b(2), b(3),…., b(n)).

The below does not look like much, but it uses a powerful MATLAB facility:
t = num2cell(b);
