Convert sparse matrix to banded matrix.

Pascal
procedure SparseToDense(const Dst: TMtx; MaxElemCount: integer = 10000000);
Description

Convert sparse matrix modified compressed column format to dense matrix.

Example

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!');
