TOpenCLMatrix::StdDev Method

Overload List

#	Signature	Description
1	double StdDev();	Standard deviation.
2	double StdDev(int Index, int Len);	Returns the standard deviation of calling object elements [Index]..[Index+Len-1].
3	double StdDev(double ASum, double aSumSqr);	Returns the standard deviation of all calling object elements.
4	double StdDev(double ASum, double aSumSqr, int Index, int Len);	Returns the standard deviation of calling object elements [Index]..[Index+Len-1].

Overload 1: double StdDev();

Standard deviation.

Remarks:

Calculate the standard deviation of all calling object elements. The result is a real value. An exception is raised if calling vector TOpenCLBase::Complex property is true.

Examples

#include "clMtxVec.h"
#include "Units.clMtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::ClMtxVec;

void Example()
{
    TOpenCLVector* a;
    CreateIt(a);
    a->CopyFromArray(DewArray<double>{-1,2,-3,4});
    double c = a->StdDev();
    FreeIt(a);
}

Overload 2: double StdDev(int Index, int Len);

Returns the standard deviation of calling object elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Index	int
2	Len	int

Remarks:

An exception is raised if calling object TOpenCLBase::Complex property is true or if array borders are overrun/underrun.

Overload 3: double StdDev(double ASum, double aSumSqr);

Returns the standard deviation of all calling object elements.

#	Name	Type	Description
1	ASum	double
2	aSumSqr	double

Remarks:

The sum and the sum of squares of all calling object elements must be passed as parameters. An exception is raised if calling object TOpenCLBase::Complex property is true.

Overload 4: double StdDev(double ASum, double aSumSqr, int Index, int Len);

Returns the standard deviation of calling object elements [Index]..[Index+Len-1].

#	Name	Type
1	ASum	double
2	aSumSqr	double
3	Index	int
4	Len	int

Remarks:

The sum and the sum of squares of the coresponding elements must be passed as parameters. An exception is raised if calling object TOpenCLBase::Complex property is true or if array borders are overrun/underrun.
