Example

Step 1: Construct dense matrix,

var A,B: Matrix; SparseA: TSparseMtx; /// ... A.SetIt(3,3,false,[1,0,0,0,2,0,0,1,3]);

Step 2: Convert dense matrix to sparse matrix

/// ... SparseA.DenseToSparse(A);

Step 3: Convert sparse matrix back to dense and compare

/// ... SparseA.SparseToDense(B); if not A.Equal(B,1.0e-5) then ERaise('Not Equal!');
