MatrixInt.SetVal Method

Overload List

#	Signature	Description
1	function SetVal(const Value: Integer): TMtxInt;	Set all calling object elements to Value.
	└ indexed: function SetVal(const Value: Integer; const Index: Integer; const Len: Integer): TMtxVecInt;
2	function SetVal(const Value: Integer; Row: Integer; Col: Integer; ToRow: Integer; ToCol: Integer): TMtxInt;	Initializes matrix values to Value.

Overload 1: function SetVal(const Value: Integer): TMtxInt;

Set all calling object elements to Value.

#	Name	Type	Description
1	Value	Integer

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

Indexed: function SetVal(const Value: Integer; const Index: Integer; const Len: Integer): TMtxVecInt;

Set calling object elements [Index]..[Index+Len-1] to Value.

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

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

Remarks:

An exception is raised if array borders are overrun/underrun.

Examples

Uses MtxExprInt;

procedure Example;
var a:MatrixInt;
begin
    a := [[1,2],[3,4]];
    a.SetVal(5,2,2); // a = [1,1,5,5]
end;

Overload 2: function SetVal(const Value: Integer; Row: Integer; Col: Integer; ToRow: Integer; ToCol: Integer): TMtxInt;

Initializes matrix values to Value.

#	Name	Type
1	Value	Integer
2	Row	Integer
3	Col	Integer
4	ToRow	Integer
5	ToCol	Integer

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

Remarks:

Sets the calling matrix elements [Row,Col]..[ToRow,ToCol] to Value. An exception is raised if TMtxVecBase.ConditionCheck is true and array bounds are overrun.
