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

Pascal
function Sgn(const Src: TOpenCLMtxVec; SrcIndex: integer; Index: integer; Len: integer): TOpenCLMtxVec; overload;
Description

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