TMtxInt.SortDescend Method

Overload List

#	Signature	Description
1	function SortDescend: TMtxInt;	Sorts the elements in a matrix row(s) in descending order.
	└ indexed: function SortDescend(Index: Integer; Len: Integer): TMtxVecInt;
2	function SortDescend(Col: Integer): TMtxInt;	Performs row based sort in descending order. The Col parameter defines the column based on which the rows are compared with each other.
3	function SortDescend(DstSortIdx: TMtxVecInt; SortIdxIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;	Sort all calling vector elements in descending order in-place.

Overload 1: function SortDescend: TMtxInt;

Sorts the elements in a matrix row(s) in descending order.

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

Remarks:

Sorts the elements in calling matrix row(s) in descending order in-place.

Note
Each row is sorted independently from the other.

Examples

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

Indexed: function SortDescend(Index: Integer; Len: Integer): TMtxVecInt;

Sort calling vector elements [Index..Index+Len-1] in descending order in-place.

#	Name	Type	Description
1	Index	Integer	start index
2	Len	Integer	element count

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

Overload 2: function SortDescend(Col: Integer): TMtxInt;

Performs row based sort in descending order. The Col parameter defines the column based on which the rows are compared with each other.

#	Name	Type	Description
1	Col	Integer

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

Overload 3: function SortDescend(DstSortIdx: TMtxVecInt; SortIdxIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Sort all calling vector elements in descending order in-place.

#	Name	Description
1	DstSortIdx	After execution stores sorted values indices.
2	SortIdxIndex	The starting index at which to store sorted values indices in DstSortIdx.
3	Index	The starting index at which to start the sort.
4	Len	The number of elements to sort starting from including zero-based Index.

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

Returns: calling vector, storing sorted values.

Remarks:

Size of DstSortIdx and calling vector are adjusted automatically.
