Dear ALL

Supose that we have an matrix, lets say a[200,200]
most of the elements are 0
I want to find the coordinates and the values of the elements that are
not zero within the matrix
(eg valye 5, col 12, row 17)

if i give the commanf

index=WHERE(a gt 0)
then the result is a long aray of dimesion 1.

any suggestions?

Thank You in advance

Kostas
