TSparseMtx.Size Methods

Summary

Define the size of sparse matrix.

Declaration

Function Size(AMtxVec: TMtxVec; AComplex: boolean): TMtxVec;

Description

Define the calling matrix size to match those of the AMtxVec objects. If AComplex is true, calling sparse matrix Complex property is set to true.

Example 1

          SparseA.Size(3,4,5,false);
          // is the same as calling this sequence
          SparseA.Complex := false;
          SparseA.Rows := 3;
          SparseA.Cols := 4;
          SparseA.NonZeros := 5;

          SparseA->Size(3,4,5,false);
          // is the same as calling this sequence
          SparseA->Complex = false;
          SparseA->Rows = 3;
          SparseA->Cols = 4;
          SparseA->NonZeros = 5;

Declaration

Procedure Size(RowCount, ColCount, NonZeroCount: integer; IsComplex: boolean = false);

Description

Define the sparse matrix size to RowCount Rows, ColCount Cols, NonZeroCount non-zero elements (the NonZeros property) and define the matrix to be complex if IsComplex is true.
