Overload List

#SignatureDescription
1function Abs: TOpenCLMtxVec;Absolute values.
└ indexed: function Abs(Index: Integer; Len: Integer): TOpenCLMtxVec;
2function Abs(const X: TOpenCLMtxVec): TOpenCLMtxVec;Calculate the absolute value for all X object and store the results in the calling object.
└ indexed: function Abs(const X: TOpenCLMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function Abs: TOpenCLMtxVec;

Absolute values.

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

Remarks:

Calculate the absolute value of all calling object elements in-place.

Examples
var A,B: clVector;
begin
    A.CopyFromArray(TSingleArray.Create(1,-2,3,4));
    B.Abs(A);  // B = [1,2,3,4]
end;

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

Calculate the absolute value for calling object elements [Index]..[Index+Len-1].

#NameTypeDescription
1IndexIntegerstart index
2LenIntegerelement 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 Abs(const X: TOpenCLMtxVec): TOpenCLMtxVec;
