Vector::Scale Method

Overload List

#	Signature	Description
1	TMtxVec Scale(double* Factor) const;	Multiply object elements with Value.
2	TMtxVec Scale(double* Factor, int Index, int Len) const;	Multipy calling object elements [Index]..[Index+Len-1] with Value in-place.
3	TMtxVec Scale(TCplx Factor) const*;	Multiply all calling object elements with a complex Value in-place.
4	TMtxVec Scale(TCplx Factor, int* Index, int Len) const;	Multipy calling object elements [Index]..[Index+Len-1] with complex Value in-place.

Overload 1: TMtxVec *Scale(double Factor) const;

Multiply object elements with Value.

#	Name	Type	Description
1	Factor	double

Remarks:

Multiply all calling object elements with Value in-place. This method is the same as the Vector::Mul method overloads multiplying with vector elements with a scalar.

Examples

#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector v;

    v.SetIt(false, DewArray<double>{2, 3, 5}); // v = [2,3,5]
    v.Scale(3); // v = [6,9,15]
}

Overload 2: TMtxVec *Scale(double Factor, int Index, int Len) const;

Multipy calling object elements [Index]..[Index+Len-1] with Value in-place.

#	Name	Type
1	Factor	double
2	Index	int
3	Len	int

Remarks:

An exception is raised if array borders are overrun or underrun.

Examples

#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector v;

    v = {2, 3, 5}; // v = [2,3,5]
    v.Scale(3); // v = [6,9,15]
}
