Using the sparse array example: julia> using SparseArrays julia> A = sparse([1, 2, 3], [1, 2, 3], [0, 2, 0]) 3×3 SparseMatrixCSC{Int64,Int64} with 3 stored entries: [1, 1] = 0 [2, 2] = 2 [3, 3] = 0 How can I get all the pairs that are set even though the value may be 0, i.e (1,1), (2,…

Getting all set values of a sparse matrix

See ?findnz:

julia> I, J, V = findnz(A)
([1, 2, 3], [1, 2, 3], [0, 2, 0])
