Step 1: Construct dense matrix

          var A,B: TMtx;
          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!');
