TOpenCLMatrix.Mean Method

Overload List

#	Signature	Description
1	Double Mean	Mean value.
	└ indexed: Double Mean(Int32 Index, Int32 Len)
2	void Mean(ref TCplx AMean)	Same as Dew.Math.TOpenCLMtxVec.Meanc.
	└ indexed: void Mean(ref TCplx AMean, Int32 Index, Int32 Len)
3	void Mean(ref Double AMean, Int32 Index, Int32 Len)	Calculate the mean value from calling object elements [Index]..[Index+Len-1].

Overload 1: Double Mean

Mean value.

Returns: Double

Remarks:

Calculate the mean value of all calling object elements. The result is a real value. An exception is raised if calling object Dew.Math.TOpenCLBase.Complex property is true.

Examples

clMatrix a;
double b;
a.Size(2,2, clFloat, false);
a.CopyFromArray(TDoubleArray.Create(1,2,3,4));
b = a.Mean; // b = 2.5

Indexed: Double Mean(Int32 Index, Int32 Len)

Returns real mean value from calling object elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Index	Int32	start index
2	Len	Int32	element count

Returns: Double

Remarks:

An exception is raised if calling object Dew.Math.TOpenCLBase.Complex property is true or array borders are overrun.

Overload 2: void Mean(ref TCplx AMean)

Same as Dew.Math.TOpenCLMtxVec.Meanc.

#	Name	Type	Description
1	AMean	TCplx (ref)	pre-computed mean

Result: stored in self (calling object)

Indexed: void Mean(ref TCplx AMean, Int32 Index, Int32 Len)

Same as Dew.Math.TOpenCLMtxVec.Meanc.

#	Name	Type	Description
1	AMean	TCplx (ref)	pre-computed mean
2	Index	Int32	start index
3	Len	Int32	element count

Result: stored in self (calling object)

Overload 3: void Mean(ref Double AMean, Int32 Index, Int32 Len)

Calculate the mean value from calling object elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	AMean	Double (ref)	pre-computed mean
2	Index	Int32	start index
3	Len	Int32	element count

Result: stored in self (calling object)

Remarks:

The result AMean is a real value. An exception is raised if calling object Dew.Math.TOpenCLBase.Complex property is true or array borders are overrun/underrun.
