Triangular Matrix

I want to get a Mapping Function for following sparse matrix of size
NxN , where N is odd
-----------------------------------------------------------------------------------
0 0 0 0 0 ... 0 a1,n
0 0 0 0 0 ... ... 0 0
0 0 0 0 0 ... a3,n-2 a3,n-1 a3,n
0 0 0 0 0 .. ... 0 0
0 0 0 ... a5,n-4 a5,n-3 a5,n-2 a5,n-1 a5,n
.... .... ... ... ... ... .. ...
.......................................................................
.......................................................................
0 0 0 0 0 ..... 0 0 0
an1 an2 an3 an4 an5 ... an,n-2 an,n-1 an,n
-------------------------------------------------------------------------------------

Suggest a mapping function to map the elements of the matrix onto a
single dimensional array
in which zero "0" elements do not have representation.

Please, any body could find mapping function formula for this kind of
Matrix.
