Sparse Function for any matrix

I am trying to write a sparse function code for any matrix size. For example if i have a matrix:

        A = [ 0   0   0   5
              0   2   0   0
              1   3   0   0
              0   0   4   0];
          for i=1:a for j=1:b if A(i,j) ~=0

S --> is the storage matrix for all the non zero elements for A matrix. In addition to this information(Index,Row Number, Column Number, Value) how do I include two more columns in the matrix which shows the next element in row & the next element in column.
