How to input a position in a matrix?

I am trying to write a function that takes an input of a m by n matrix and also a 2 element 1D array that represents a position in the given matrix. For example, if I had an array of E=[3 6 3 7 2 5;1 4 2 4 1 4; 7 9 5 6 9 2; 10 8 4 3 10 5] and I wanted to start at position E(3,3) = 5, how would I go about having these both given as a user input?

%
 A={1 2 3;4 5 6}
 % If you want to locate any position suppose
 A{2,2} % Go to the particular position>> its go to 5 value element
 % Define any position using A{i,j}
