Overload List

#SignatureDescription
1function Sgn: TOpenCLMtxVec;Computes signum function of calling object elements.
└ indexed: function Sgn(Index: Integer; Len: Integer): TOpenCLMtxVec;
2function Sgn(const Src: TOpenCLMtxVec): TOpenCLMtxVec;Computes signum function from Src elements and stores the result in the calling object.
└ indexed: function Sgn(const Src: TOpenCLMtxVec; SrcIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function Sgn: TOpenCLMtxVec;

Computes signum function of calling object elements.

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

Remarks:

Signum(X) is 1 for X > 0 , equal to zero for X = 0 and -1 for X < 0.

Indexed: function Sgn(Index: Integer; Len: Integer): TOpenCLMtxVec;

Computes signum function of calling object elements [Index..Index+Len-1].

#NameTypeDescription
1IndexIntegerstart index
2LenIntegerelement count

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

Remarks:

Signum(X) is 1 for X > 0 , equal to zero for X = 0 and -1 for X < 0.

Overload 2: function Sgn(const Src: TOpenCLMtxVec): TOpenCLMtxVec;

Computes signum function from Src elements and stores the result in the calling object.

#NameTypeDescription
1SrcTOpenCLMtxVecsource TOpenCLVector or TOpenCLMatrix

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

Remarks:

Size and TOpenCLBase.Complex properties of calling object are adjusted automatically. Signum(X) is 1 for X > 0 , equal to zero for X = 0 and -1 for X < 0.

Indexed: function Sgn(const Src: TOpenCLMtxVec; SrcIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Computes signum function from Src elements [SrcIndex..SrcIndex+Len-1] and stores the result in the calling object [Index..Index+Len-1].
