TOpenCLVector.Scale Method

Overload List

#	Signature	Description
1	function Scale(const Factor: TCplx): TOpenCLMtxVec;	Multiply all calling object elements with a complex Value in-place.
	└ indexed: function Scale(const Factor: TCplx; Index: Integer; Len: Integer): TOpenCLMtxVec;
2	function Scale(const Factor: Double): TOpenCLMtxVec;	Multiply object elements with Value.
	└ indexed: function Scale(const Factor: Double; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function Scale(const Factor: TCplx): TOpenCLMtxVec;

Multiply all calling object elements with a complex Value in-place.

#	Name	Type	Description
1	Factor	TCplx	scalar

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

Indexed: function Scale(const Factor: TCplx; Index: Integer; Len: Integer): TOpenCLMtxVec;

Multipy calling object elements [Index]..[Index+Len-1] with complex Value in-place.

#	Name	Type	Description
1	Factor	TCplx	scalar
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 or underrun.

Overload 2: function Scale(const Factor: Double): TOpenCLMtxVec;

Multiply object elements with Value.

#	Name	Type	Description
1	Factor	Double	scalar

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

Remarks:

Multiply all calling object elements with Value in-place. This method is the same as the TOpenCLMtxVec.Mul method overloads multiplying with vector elements with a scalar.

Examples

var v: clVector;
begin
    v.CopyFromArray(TSingleArray.Create(2,3,5));  // v = [2,3,5]
    v.Scale(3); // v = [6,9,15]
end;

Indexed: function Scale(const Factor: Double; Index: Integer; Len: Integer): TOpenCLMtxVec;

Multipy calling object elements [Index]..[Index+Len-1] with Value in-place.

#	Name	Type	Description
1	Factor	Double	scalar
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 or underrun.
