TSparseMtx::Scale Method

Overload List

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

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

Multiply object elements with Value.

#	Name	Type	Description
1	Factor	const double

Remarks:

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

Examples

#include "Units.MtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;

void Example()
{
    TVec* a;
    CreateIt(a);
    a->SetIt(false, DewArray<double>{2,3,5});  // a = [2,3,5]
    a->Scale(3); // a = [6,9,15]
    FreeIt(a);
}
