Accessing order pair from sparse matrix

Hello, my question has to do with accessing the indicies of a sparse matrix. Say we define $S=sparse(M)$, then if we put S in the command lines we'd see something like this (for example):
(1,3) 5
(2,4) 1
(2,5) 3.1415
etc...
Is there a way to just access the order pairs directly? I have two matricies with corresponding elements and want to perfome some tests around the nonzero elements of a figure I am working on. This alone would greatly simplified my code but I can not find any documentation on it...
