Overload List

#	Signature	Description
1	function Resize(const Src: TMtxInt; NewRows: Integer; NewCols: Integer): TMtxInt;	Sizes the calling matrix to NewRows and NewCols.
2	function Resize(NewRows: Integer; NewCols: Integer): TMtxInt;	Resizes the matrix, while preserving the values in already allocated memory.

Overload 1: function Resize(const Src: TMtxInt; NewRows: Integer; NewCols: Integer): TMtxInt;

Sizes the calling matrix to NewRows and NewCols.

#	Name	Type
1	Src	TMtxInt
2	NewRows	Integer
3	NewCols	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Copies the Src matrix values to the calling matrix. The elements outside the newly created matrix size are not referenced.

Overload 2: function Resize(NewRows: Integer; NewCols: Integer): TMtxInt;

Resizes the matrix, while preserving the values in already allocated memory.

#	Name	Type	Description
1	NewRows	Integer
2	NewCols	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Sets the MatrixInt.Rows property to NewRows, MatrixInt.Cols property to NewCols, while preserving the values in already allocated memory.

Examples

var  A,B: TMtxInt;
begin
    CreateIt(A,B);
    try
        A.SetIt(2,2,[1,3,
            2,4]);
        B.Resize(A,3,2);
        // B becomes:
        // [1,2,0,
        //  3,4,0]);
    finally
        FreeIt(A,B);
    end;
end;
